Abstract

A polymeric composition in pellet form comprising a tacky hot melt composition, comprising a) from about 5 % by weight to about 90 % by weight of a thermoplastic polymer, b) from about 10 % by weight to about 65 % by weight of a tackifying resin, c) up to about 50 % by weight of a plasticizer, d) up to about 2 % by weight of an antioxidant, and a pelletizing aid, wherein the tacky hot melt composition is a pressure sensitive adhesive having a storage modulus, G', at about 25 ~C, of less than about 5 x 106 dynes/cm2, and each pellet has a substantially tack-free surface. This invention further discloses a polymeric composition in pellet from suitable for molding articles. The composition comprises a tacky hot melt composition comprising at least one high molecular weight triblock copolymer of the general configuration A-B-A
and a plasticizer and a pelletizing aid. The pelletizing aid substantially surroudns the tacky composition such that the molded articles are substantially free from surface tack. A method of forming the pellets is also disclosed.
