Reaction Steps
A styrene/ethyl acrylate/acrylic acid copolymer emulsion was prepared using 384 g of a mixed monomer feed (39.7, 59.6, 0.7% by weight respectively) fed to a reaction vessel. The temperature was maintained at 60°±2° C. until polymerization was complete, using a redox system. 56.8 g of a mixture of styrene, acrylic acid and γ-methacryloxypropyl trimethoxy silane (81.3, 16.9, 1.8% by weight respectively) was then added to the polymer emulsion and polymerised under similar conditions. By this manner a shell of polymer containing Si-OH or Si-OCH3 groups in the chain around a core of styrene/ethyl acrylate copolymer was obtained.
