The preparation of copolymers of α‐methylstyrene and styrene in an emulsion system is described. At both 40 and 60°C, there was no evidence of deviation from simple kinetics. Polymers of high molecular weight and high and high α‐methylstyrene content showed good thermal properties such as T g and softening point. However, these polymers proved to be awkward to process due to a strong proclivity to degrade under shearing conditions.
