Abstract

OPAQUE PEARLESCENT FILMS CONTAINING DISPERSED
INCOMPATIPLE POLYMER AND POLYMERIC INTERFACIAL AGENT

ABSTRACT

Opaque pearlescent polymer films, e.g., polypropylene, containing finely dispersed particles of an incompatible polymer e.g., Nylon, are improved by blending a polymeric interfacial agent with the film polymer and the incompatible polymer to give a film having the incompatible polymer dispersed in smaller spherical particles and reduced stringiness.

OPAQUE PEARLESCENT FILMS CONTAINING DISPERSED
INCOMPATIBLE POLYMER AND POLYMERIC INTERFACIAL AGENT

Cpaque polymeric films in which the opacifying agent is a finely divided polymer dispersed in the continuous film polymer phase are described in U.S. Patents 4,368,295 and 49377,616. L.S.
Patent 4,368,295 discloses opaque polyester films containing dispersed polypropylene and a carboxylated polyethylene additive.
In U.S. Patent 4,377,616, a ~ilm is prepared by melting a mixture of a major proportion of a ~ilm forming polymer such as polypropylene and a minor proportion o~ an incompatible polymer which has a higher melting point, at a temperature sufficient to melt the incompatible polymer and to dispelse it in the ~ilm forming polymer, extruding the mixture into a film,and biaxially orienting the film. The dispersPd incompatible polymer provides sites for the formation of voids surrounding the dispersed polymer particles.
These vo~ds provide opacity and give the fi,lm an attractive pearlescent sheen. Reduction o~ the size of the dispersed particles and reduCtin o~ the occurrence of stringiness in those particles, as sometimes occurs, results in a film having improved opacity and better appearance. Such improvements are provided in accordance with this invention.
This invention relates to improvements in opaque polymeric films containing a finely dispersed incompa~;hle polymer as the .~i ~,.

opacifying agent. Particle size and stringiness in the dispersed incompatible polymeric phase are reduced by incorporating a polymeric interfacial agent in the mixture of polymers.
The present invention, then, in one aspect, resides in an opaque to translucent, biaxially oriented melt extruded polymeric film comprising a continuous phase of a polyolefin fir6t polymer and a polymeric interfacial agent comprising a copolymer of ethylene and a carboxyl containing monomer or a salt thereof; and a di~continuous dispersed pha~e of a finely divided second polymer comprising a polyamide or polyester which is incompatible with the first polymer, the polymeric intsrfacial agent having a polymeric moiety which is similar to the first polymer and a moiety which is more compatible with the second polymer and being present in the continuous phase in an amount su~ficient to disper~e the ~scond polymer in smallsr particles with fewer stringy particles than in a film made without the polymeric interfacial agent.
In another aspect, ths present invention resides in a method of improving dispersion of a finely divided dispersed polymeric phase in an opaqus to translucent polymeric film comprising a continuou~ phase of a polyolefin fi r~ t polymer and a dispersed phase of a 6scond polymer comprising a polyamide or polyester, which is incompatible with the first polymer, ths method comprising incorporat~ng in the continuous phase an e~fective amount of a polymeric interfacial agent comprising a copolymer of ethylene and a carboxyl containing monomsr or a salt thereof, eaid agent having a polymeric moiety whlch is similar to the ~irst polymer and a moisty which is more compatible with the second polymer 30 as to disperss the second polymer in smaller particles with fewar stringy partiale3 than in a film made withou~ the in~er~acial agent.

,~

;337 -2a -~e opaque polymeric films of this invention containing finely dispersed incompatible polymer as the opacifying agent are improved by the incorporation into the polymeric blend priûr to formation of the film of an interfacial polymeric additive. The interfacial additive generally has a polymeric moiety which is similar to the polyolefin film forming polymer and a moiety which is more compatible with the polymer of the dispersed phase. For ex~mple, thc moiety which is compatible with the polyolefin fllrn forming phase is advantageously a polyolefin moiety such as 1() polyethylene or polypropylene. The moiety which is more compatible with the dispersed phase is advantageously a carboxylic acid, carboxylic salt, carboxylic acid ester or carboxylic acid amide group. Preferably, carboxylic acid or carboxylic acid salt derivatives of ethylene or propylene copolymers are used. Such materials include copolymers of ethylene with the appropriate monomer such as acrylic acid, methacrylic acid, or esters such as acrylates, methacrylates and vinyl acetates. The carboxylic acid group can be introduced after formation of the polymer as disclosed in U~S. Patent ~,368,295. Particularly suitable are the "Surlyn"*
ionomer resins available from DuPont which are believed to be certain salts of polymers of ethylene copolymerized with a carboxylic acid monomer.
The polymeric interfacial agent is added in an amount which :Ls effective to reduce the size of the dispersed polymer particles and to reduce the stringiness observed in the dispersed polymer~
ParticulQrly effective additives will result in a film in which the dispersant size is 8 microns or less and which has very little, if any, stringiness in the dispersed phase. It is preferred to include the additive in amounts suf~icient to obtain a particle size of 5 microns or less and preferably 3 microns or less with no stringiness `:5J

d7~1337 in the particles. Generally, levels of additives in the ranye of 0.5 to 10 weight percent by weight can be used. However, excesses are to be avoided because the particle size becomes too small and opacity is reduced. Preferably, the additive is in an amount of ranging from about 1 to about 4 weight percent. About 2 weight percent has been found suitable wi~h particularly effective additives.
The methods for preparing the films described in U.S.
Patent 4,377,616 can be used herein. As described in the patent, the films can contain additional components such as inorganic fillers and the like. Similarly, the films can contain one or more additional layers to achieve high gloss1 heat sealability or other desired characteristics.
The invention is illustrated by the following non-limiting examples. All parts are by weight unless otherwise specified.

A series of films ~rom resin blends comprising lS weight percent Nylon-6 tAllied 8207F), the indicated amount of polymeric interfacial additive, the remainder being polypropylene, were prepared Extrusion tests were conducted by dry blending resin mixtures and cast extruding the blends into 0.25 mm (10 mil) sheets usinq a 19 mm (3/4") Brabender extruder equip~ed wi~ a ~sta~e mixing screw. The sheets were then biaxially oriented on a ~.M.
Long Orientor.
The distribution of the resin components in the extrudate were examined optically. The surface and the cross-sections of the cast films were stained with aqueous iodine solution for one minute and then examined under an optical microscope. Polar components, such as nylon appeared as dark brown areas, while the polypropylene was not affected by the staining.
