Ceramic tile adhesives
First Claim
1. An aqueous emulsion polymer composition for use as a ceramic tile adhesive, which composition contains a large quantity, based on the weight of solid polymer, of filler material and an emulsion polymer of at least one acrylate monomer selected from acrylates and methacrylates and at least one vinyl aromatic monomer, which emulsion polymer is prepared in the presence of at least one unsaturated organo-silicon compound to improve retention of adhesive strength of the adhesive composition on exposure to moisture.

Abstract
An adhesive for the efficient bonding of ceramic tiles and having improved water resistance comprises an emulsion copolymer composition including an acrylate or methacrylate monomer, a vinyl aromatic monomer, and, for reducing water sensitivity, an unsaturated organo-silicon compound. Compositions which are effective in promoting water resistant adhesion may contain as little as from 0.1-1.0% by weight of the unsaturated organosilicon compound.
