Abstract: A non-crosslinked endblocked polymer, comprising a preformed aqueous emulsion having a plurality of silanol-terminated polydiorganosiloxane particles, an endcapping silane having the formula R.sub.3 SiX where X is a hydrolyzable group, R is an alkyl group consisting of 1 to 7 carbon atoms, and an organotin catalyst.
