Abstract:
1. A composite polymer emulsion comprising a composite polymer from polymerizing an aliphatic olefin copolymer in a media containing a support resin, water with a free radical initiator source; said aliphatic olefin copolymer comprising repeating units from a) at least one ethylenically unsaturated aliphatic olefin with 4 to 28 carbon atoms with b) at least one ethylenically unsaturated monomer containing an electron withdrawing group, and c) optionally with other ethylenically unsaturated monomers, the polymerization composite polymer in water being at least partially colloidally stabilized by said support resin, wherein said polymeric support resin comprises i) from about 5 to about 40 wt. % of repeating units derived from acrylic acid or methacrylic acid or ii) from about 10 to about 30 wt. % repeating units from an unsaturated co-polymerizable dicarboxylic acid.
