ABSTRACT OF THE DISCLOSURE There is presented a new process for producing homopolymers and copolymers of vinyl and vinylidene halides by means of the suspension polymerization procedure. In this new process, the reactor is run a few degrees warmer than normal for the first part of the reaction and then followed by a steadily decreasing temperature throughout most of the rest of the polymerization in order to linearize the reaction rate. This allows one to charge more initiator and/or monomer to the reactor thereby increasing produc- tivity per unit of time.
