Abstract:
A latex polymer of multi-stage polymerization comprising a first stage polymer and a second stage polymer wherein the first stage polymer comprises a first portion of an acrylic monomer and a first portion of a phosphorus acid monomer, and the second stage polymer comprises a second portion of an acrylic monomer and a second portion of a phosphorus acid monomer. A process of making such latex polymer.
