STABILITY OF EMULSIFIER-FREE EMULSION COPOLYMERIZATION OF METHYL METHACRYLATE/BUTYL ACRYLATE/SODIUM MONO(ETHYL POLYOXYETHYLENE)MALEATE

Received Date: 14 December 1998

A series of new water-soluble bifunctional comonomers having both carboxyl and alkylpolyoxyethylene groups, such as sodium mono(ethyl polyoxyethylene) maleate (ZE series) with variousmolecular weights of polyoxyethylene ethyl ether, were synthesized and characterized. The effects of thestructural factor, the amount and feeding mode of the comonomers, the initiator concentration andpolymerization temperature on the stability of emulsifier-free emulsion copolymerization of methylmethacrylate (MMA) and butyl acrylate(BA) in the presence of a small amount of ZE with potassium persulfate as initiator were investigated.Stable almost monodispersed MMA/BA/ZE emulsifier-free latex particles were prepared.
