Synthesis and Film‐forming Properties of Chlorinated Polystyrene

A large number of resins and polymers are used as film formers. These have been undergoing modifications to meet the growing demand. One of the modifications involves chlorination and products like chlorinated rubber, chlorinated biphenyls, chlorinated paraffins, chlorinated poly(vinyl chloride), chlorinated polyethylene, chlorinated polypropylene and chlorinated polyether are the result. Besides these well‐established chlorinated products, chlorinated drying and semi‐drying alkyds, chlorinated epoxy esters and chlorinated acrylic polymers have also been studied.
