ABSTRACT:
A mercapto-functional silicone fluid is prepared by hydrolyzing a mercapto-silane and an organosilane, with a weak acid. The hydrolyzate is, then, reacted in the presence of an acid with a mixture of an end-blocking polyalkylpolysiloxane and a chain-extender which is either a cyclic polysiloxane or an alkyl-terminated or hydroxy-terminated silicone fluid.
