Double Roles of Stabilization and Destabilization of Initiator Potassium Persulfate in Surfactant-Free Emulsion Polymerization of Styrene under Microwave Irradiation†

We resolved the longtime enigma in emulsion polymerization of styrene with K2S2O8 by showing the fact that hollow polystyrene particles were successfully prepared by heat treatment in the emulsion state.

Soap Free Emulsion Polymerization

In this paper, a sizing agent applied in papermaking was synthesized via emulsion polymerization using styrene (St), methyl acrylic acid (MAA), methyl methacrylate (MMA) and butyl acrylate (BA) as monomer. In this process, potassium persulfate (KPS) was used as a initiator and sodium lauryl sulfate (SDS) and OP-10 were used as the emulsifier or no emulsifier was used, while NB2Bwas used as a protective atmosphere for the reaction system. The product of emulsion polymerization with St and BA has a good comprehensive properties and a certain sizing effectiveness. Furthermore, the microwave irradiation could not only produce emulsions with small diametric particles but also shorten the polymerized time greatly.
