Abstract
PURPOSE: The reaction between a specific polycarbosilane and an organozirconium compound affords the titled compound giving a formed product containing SiC-ZrC by calcination with high mechanical properties and oxidation resistance at high temperatures.
CONSTITUTION: (A) A polycarbosilane having the main chain skelton of the formula (R is H, lower alkyl, phenyl) and a number-average molecular weight of 200W10,000 and (B) an organozirconium compound of ZrX4 (X is 1W20C alkoxy, phenoxy, acetylacetoxy) are combined so that the ratio of the total number of -SiCH2- structural units in component A to the total number of -ZrO- structural units in component B becomes 2/1W200/1 and they are made to react by heating in an inert atmosphere to bind at least a part of Si atoms in component A through oxygen atoms with Zr atoms in component B, thus producing the objective compound of 700W100,000 number-average molecular weight.
