Gradual Addition of Initiator in the Suspension Polymerization of Styrene Monomer

Gradual addition of initiator in the suspension polymerization of styrene monomer for the production of expandable polystyrene has been investigated in this paper. It is found, that combination of gradual addition of conventional peroxide and raising the polymerization temperature, resulted in a product with properties such as an average molecular weight and residual monomer contents, similar to that of the conventional product and in a shortened polymerization time
