  • Emulsion polymerization composition
    Patent number: 5286779
    Abstract: An emulsion polymerization composition comprises: (a) 1-45% by weight of an emulsion polymerizable monomer, (b) 0.1-5% by weight of an emulsifier and stabilizer which is a copolymer of a vinyl lactam and a polymerizable carboxylic acid, in a 99/1 to 1/99 weight ratio, (c) 1-10% of a surfactant based on monomer, preferably 2-6%, (d) 0.1-2%, preferably 0.2-1%, by weight of a polymerization initiator, and (e) the rest being water, in the form of an aqueous dispersion.
    Type: Grant
    Filed: March 10, 1993
    Date of Patent: February 15, 1994
