Abstract:
1. A process for producing an aqueous coating composition comprising the steps of: forming a melt blend of one or more base polymers, one or more polar polymeric stabilizing agents, and one or more hydrophobic particulate fillers, wherein the one or more base polymers are selected from the group consisting of ethylene/acrylic acid copolymers and ethylene/methacrylic acid copolymers; injecting an initial amount of water and neutralizing agent into said melt blend; melt kneading said melt blend, optionally in the presence of further neutralizing agent, under elevated pressure and heat sufficient to eliminate steam pressure build-up; thereby forming an aqueous dispersion of particles, the particles comprising:
