Preceramic polymeric compounds based on polycarbosilane and diallylbisphenol A

Preceramic polymeric compounds based on polycarbosilane and diallylbisphenol A Preceramic compounds based on polycarbosilane and 2,2′-diallylbisphenol A with different weight ratios of the starting components were investigated. According to the data of gel permeation chromatography, simultaneous thermal analysis, and IR spectroscopy, the mixture components chemically react in the temperature interval 100–400°C to form a cross-linked high-molecular-mass product. The temperature conditions of the processing of the preceramic compounds, allowing preparation of a matrix containing up to 70 wt % cross-linked polymer in an inert medium, were found. The temperature intervals of the pyrolysis of the cured compounds were determined by simultaneous thermal analysis. It was found that the yield of the ceramic matrix could be increased by 30% relative to pure polycarbosilane. Evaluation of the thermal oxidation resistance of the ceramic pyrolysis products, performed by simultaneous thermal analysis in air, showed that the weight change of the compound samples on heating to 1200°C did not exceed 0.1%, irrespective of their composition. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Applied Chemistry Springer Journals

Abstract

Preceramic compounds based on polycarbosilane and 2,2′-diallylbisphenol A with different weight ratios of the starting components were investigated. According to the data of gel permeation chromatography, simultaneous thermal analysis, and IR spectroscopy, the mixture components chemically react in the temperature interval 100–400°C to form a cross-linked high-molecular-mass product. The temperature conditions of the processing of the preceramic compounds, allowing preparation of a matrix containing up to 70 wt % cross-linked polymer in an inert medium, were found. The temperature intervals of the pyrolysis of the cured compounds were determined by simultaneous thermal analysis. It was found that the yield of the ceramic matrix could be increased by 30% relative to pure polycarbosilane. Evaluation of the thermal oxidation resistance of the ceramic pyrolysis products, performed by simultaneous thermal analysis in air, showed that the weight change of the compound samples on heating to 1200°C did not exceed 0.1%, irrespective of their composition.
