- the rubber-modified resin of the present invention can maintain the flame-retardant level of the polycarbonate / polyethylene terephthalate mixed resin flame-retarded with a silicone-based or phosphorus-based flame retardant while maintaining the flame-retardant level. It can be seen that the impact property can be improved.
- a vinyl-based monomer is polymerized in the presence of a silicone rubber latex and an acryl-based rubber latex, and the polymer particles undergo coagulation and co-expansion during the polymerization.
- An improved rubber-modified resin can be obtained.
- the rubber-modified resin can be applied to various thermoplastic resins as an impact modifier, and the thermoplastic resin composition comprising the rubber-modified resin and the thermoplastic resin has excellent impact resistance.
