| titleOfInvention | Preparation of alkoxy-terminated poly(diorganosiloxsane) |
| abstract | PURPOSE: To easily prepare an alkoxy-terminated poly(diorganosiloxane) by reacting an α,ω-dihydroxypoly(diorganosiloxane) with an alkoxysilane in the presence of a specific catalyst and then, neutralizing the product. n CONSTITUTION: (A) in the presence of a catalyst composed of a strongly basic alkali metal compound (preferably a hydroxide, a silanolate or its alkoxylate of K, Na), an α,ω-dihydroxypoly(diorganosiloxane) and a tetraorganyloxywsilane or triorganyloxy organosiloxne are reacted and (B) after the desired reaction but before the initiation of rearrangement reaction adversely affecting the product, a neutralizing agent (suitably, dimethyl-dichlorosilane, etc.) is added to the reaction mixture to neutralize the product and thus, a triorganyloxysilyl- or diorganyloxyorganosilyl-terminated poly(diorganosiloxane) is prepared without by-producing corrosion polymers at a low reaction temperature for a short reaction time in an inexpensive, simple step. n COPYRIGHT: (C)1992,JPO |
