摘要:
There is disclosed a process of dispersion-polymerizing vinyl monomers promoted by free-radical catalysts. This process comprises dispersing under stirring in water a block copolymer of the A-B type wherein A represents a lipophilic block and B a hydrophilic block, adding one or more vinyl monomers containing the promoter and heating the mixture with stirring to the desired temperature. This process enables beads or balls of the desired polymer to be obtained having very regular size distribution.
