Composite of high melting polymer and nanoclay with enhanced properties

Abstract

Composite of high melting polymer and nanoclay converted so the balancing cation is quaterized copolymer of styrene and 2-(dimethylamine)ethyl methacrylate provides transparent form without coloration and enhanced modulus and strength without loss of elongation and toughness.
