Styrenic Copolymers having Maleic Anhydride Units as Reactive Compatibilizer for ABS and Engineering Plastic Alloys

Reactive compatibilizers which have functional groups such as cyclic anhydride and epoxide are widely used in immiscible polymer blends. Denka IP is styrene - N-phenylmaleimide - maleic anhydride copolymer developed by Denka’s unique technology. The main application of Denka IP is the heat resistant modifier for ABS because Denka IP is miscible with SAN phase of the ABS and has high heat resistance. Denka IP also allows reactive compatibilizer for ABS and engineering plastics alloys such as PA6/ABS. Maleic anhydride groups of the Denka IP can react with the end groups of the PA6 and graft copolymer can be formed in site during the extrusion processing of PA6/ABS alloy. As the results, the ABS domains in alloys become smaller and super-tough PA6/ABS alloys can be obtained. Now we have developed a new approach for improving the properties of PC/ABS alloy using Denka IP and our new copolymers.
