Abstract

PURPOSE: To prepare the titled compound capable of giving a thermoset product having excellent heat resistance and adbesivity, and also giving a composition having excellent adhesivity and film strength in combination with a crosslinking agent, by the dehydrative condensation of an intermediate obtained by the hydrolysis of C6H5SiCl3, in the presence of a specifici catalyst.
CONSTITUTION: A hydroxy-terminated intermediate (A) prepared by the hydrolysis of C6H5SiCl3 is dissolved in an organic solvent (pref. a water-insoluble solvent) to obtain a solution having a concentratin of ≤70wt%. The intermediate (A) is subjected to the dehydrative condensation e.g. at 120°C for 4hr using pref. 0.1W 0.2pt.wt., based on 1pt.wt. of the intermediate (A), of a carbodiimide such as dibenzyl carbodiimide as a condensation catalyst. The precipitated urea derivative is separated by filtration, and the reaction liquid is poured into methanol to obtain the objective compound of formula and having number-average molecular weight of 1,000W500,000.
