POLYALKOXYSILYL-TERMINATED POLYDIORGANOSILOXANES, METHODS FOR THEIR PREPARATION, AND ROOM TEMPERATURE VULCANIZABLE COMPOSITIONS CONTAINING THEM Abstract Polyalkoxysilyl-terminated polydiorganosiloxanes which are relatively stable in viscosity over prolonged storage periods are prepared by endcapping a silanol-ter- minated polydiorganosiloxane in the presence of a catalytic amount of an acidic amine salt which subsequently decomposes to substantially inert products, preferably an amine salt of formic acid, and in the absence of silicon nitrogen com- pounds and enoxysilanes normally used as catalyst quenchers and scavengers. The products are useful for the preparation of scavenger-free room temperature vulcanizable composi- tions, particularly when combined with certain N-alkoxy- silylalkyl-substituted compounds as adhesion promoters.
