ABSTRACT:
A block copolymer dispersion stabilizer for use in the aqueous dispersion polymerization of an ethylenically unsaturated monomer comprises at least two blocks linked by chemical valences. At least one of the blocks is hydrophilic (water soluble) and at least another of said blocks is hydrophobic (water insoluble). The hydrophobic block can contain a plurality of similar or dissimilar pendent groups having chemically reactive functionality. Examples of such groups are epoxy groups and ethylenically unsaturated bonds. An aqueous dispersion polymerization process utilizes water as the dispersion medium, a free-radical polymerization catalyst, a block copolymer dispersion stabilizer comprising at least two blocks linked by chemical valences wherein at least one of said blocks is hydrophilic and at least another of said blocks is hydrophobic and can contain a plurality of similar or dissimilar pendent groups having chemically reactive functionality, and a polymerizable ethylenically unsaturated monomer such as, for example, styrene, vinyl acetate, acrylonitrile, methyl methacrylate, butadiene, styrenebutadiene mixtures, and acrylonitrile-styrene mixtures.
