Abstract:
A process for the production of an aqueous polymer dispersion, comprising:(a) introducing into a reactor an aqueous dispersion or solution containing at least one hydrophilized fat/oil selected from the group consisting of vegetable fats/oils, animal fats/oils and technical fats/oils and combinations thereof and the total amount or a predominate amount of (a) a monoethylenically unsaturated monomer containing partially or completely neutralized acid groups and optionally (b) additional copolymerizable monomers, wherein the ratio of monomers (a) and (b) to hydrophilized fats/oils ranges from 20:80 to 80:20 and optionally a chain transfer agent;(b) initiating polymerization of the monomers by mixing a water-soluble redox system into the monomer containing polymerization medium;(c) heating the polymerization medium adiabatically; and(d) adding any remaining monomer to the polymerization medium to complete the polymerization process.
