MICROEMULSION SEEDED POLYMERIZATION OF STYRENE

Microemulsion seeded polymerizations of styrene were studied with gamm a ray or potassium persulfate. After examining the size of polymer par ticles and its distribution before and after polymerization, it was fo und that there were no new particles formed during polymerization, des pite that there were micelles in aqueous phase, These micelles acted a s monomer reservoir during polymerization, instead of nucleating loci, Due to the lower monomer content and the much more polymer particles in microemulsion seeded polymerization, its polymerization behavior wa s much different from the emulsion seeded polymerization.
