Patent ID: 8575256

Claim:
A urethane-olefin-acrylic polymeric reaction product as a interpenetrating polymer network of the polyurethane and polyolefin-acrylic dispersion in aqueous media comprising: a) a urethane prepolymer derived from reacting at least polyisocyanates with one or more active-hydrogen containing compounds, b) an olefin-acrylic copolymer derived from free radically polymerizing b1) at least one ethylenically unsaturated aliphatic olefin with 2 to 30 carbon atoms with b2) at least one ethylenically unsaturated monomer containing an electron withdrawing group, and b3) optionally with other ethylenically unsaturated monomers, wherein said b1), b2), and optional b3) form said olefin-acrylic copolymer comprising repeating units within the same copolymer from said olefin and said monomer containing an electron withdrawing group.
