Thermoplastic compositions including inorganic particulates

摘要

An improved thermoplastic composition includes an inorganic particulate dispersed in a thermoplastic, for example, an inorganic pigment such as titanium dioxide dispersed in a polyolefin as a color concentrate, wherein the inorganic particulate includes a surface coating comprised of at least one alkenyl- or alkyl-substituted succinic anhydride, for example, hexadecenylsuccinic anhydride and dodecenylsuccinic anhydride.
