Abstract
Abstract Polysiloxanes produced by polymerizing a monomeric silane in the presence of an organo metallic polymerisation catalyst, e.g. a metal carboxylate, and the use of the polysiloxanes to react with alkylene-alkyl acrylate copolymers to produce silane-modified, water-curable polymers. The polysiloxanes have the general formula: wherein R is a hydrocarbon radical or an oxy-substituted hydrocarbon radical, R 1 is a hydrocarbon radical, each V is hydrogen, a hydrocarbon radical or a hydrolyzable group, Z is an alkoxy radical having one to 18 carbon atoms inclusive, n is an integer having a value of one to 18 inclusive and x is an integer having a value of at least 2.
