The Effect of Initiator on Acrylate Emulsion Copolymerization Containing Hydroxyl Groups

Emulsion polymerization has become the important method to obtain polymer. A typical emulsion polymerization recipe comprises of monomer, emulsifier, initiator and other necessary ingredient. Among the recipe component the initiator takes up an exceptional position for a number of reasons： （1） determine the reaction temperature; （2） Influence polymer properties and end-use; （3） Cause some effect on particle morphology. Klaus etc. described the role of initiator in emulsion polymerization, and studied the influence of initiator on polymer properties taken styrene as example. Mukul etc. studied the kinetic of emulsion copolymerization of methylmethacrylate and ethylacrylate. The aim of this paper is to investigate the effect of initiator on the acrylate emulsion copolymerization with hydrophilic monomer （hydroxylethyl methacrylate, HEMA）.
