ABSTRACT:
There is provided inherently tacky pressure-sensitive adhesive polymers prepared by emulsion polymerization and containing an interpolymerized amount of a reactive silicone acrylate polymer, an unsaturated carboxylic acid one or more alkyl acrylates, preferably a mixture of butyl acrylate and 2-ethylhexyl acrylate. Methyl acrylate and vinyl acetate are optionally present. The polymers have initial repositionability, long term permanence and excellent water resistance.
