Thermal properties and resistance to crazing of copolymers and terpolymers of 2,5‐dichlorostyrene and 3,4‐dichlorostyrene have been studied. Copolymers based on 2,5‐dichlorostyrene showed little or no improvement over polystyrene in craze resistance or glass transition temperature. Although copolymers of 3,4‐dichlorostyrene were generally brittle and crazed readily, poly(3,4‐dichlorostyrene‐co‐2‐ethylhexyl methacrylate) and poly(3,4‐dichlorostyrene‐co‐ n ‐hexyl methacrylate) crazed less readily than polystyrene.
