MULTILAYER EXTRUDED SHEET HAVING A HIGH ADHESIVE STRENGTH ON SURFACE

摘要

An extruded multi-layer sheet with enhanced adhesive strength on the interface is provided to restrain layers from being separated and to secure high strength, scratch resistance, and reusability by using metal free rubber-modified styrene resin or rubber-modified styrene resin and a compatibilizer together. An extruded multi-layer sheet with enhanced adhesive strength on the interface is composed of an inner layer made of metal free rubber-modified styrene resin produced by continuous bulk polymerization and a surface layer made of thermoplastic resin. Metal free rubber-modified styrene resin consists of metal free rubber-modified styrene resin of 60~100wt.% having the rubber particle diameter of 0.5~5 micrometers, produced by continuous bulk polymerization and metal free rubber-modified styrene resin of 0~40wt.% having the rubber particle diameter of 0.1~0.5 micrometers, produced by continuous bulk polymerization.
