Being different from other dispersion polymerizations which use nonpolar fatty hydrocarbons or methanol-water as media
this article present the preparation of poly(methyl methacrylate) particles in alcohol-watermixture.In experiments
a certain heating way is applied:at first
the reaction occurs at a relatively high temperature for a given time;then the temperature is lowed and the reaction continues at that temperature to the end.This procedure results in a largely narrowed size distribution. The effects of initiator on the particle size and size distribution are also studied.It is found that even a small amount of KPS can decrease the size of particles and broaden the size distribution apparently.
