Abstract
Ar-halo-ar(t-alkyl)styrenes, e.g., 2-chloro-4-(t-butyl)styrene, polymerize to form materials having unusually high temperature resistance. Additionally, compositions of such monomers, unsaturated polyesters and free-radical generating catalysts cure at lower temperatures and in less time than similar compositions containing conventional styrene monomers.
