Abstract:
Polyarylates containing pendant silyl group were prepared by the phase‐transfer catalyzed, two‐phase polycondensations of 2,2‐bis (4‐hydroxyphenyl) propane with corresponding dicarbonyl chlorides such as 2‐trimethylsilylterephthaloyl chloride, 5‐trimethylsilylisophthaloyl chloride, 5‐dimethylphenylsilylisophthaloyl chloride, and 5‐triphenylsilylisophthaloyl chloride. The resulting amorphous polyarylates with glass transition temperatures of 163–214°C had inherent viscosities in the range of 0.41–0.95 dL/g. These polyarylates were readily soluble in common chlorinated hydrocarbons and it was possible to obtain transparent, flexible, and tough films from the polymer solutions. The prepared polyarylates showed fairly good thermal stabilities as well as tensile strengths, i.e., the tensile strengths of the cast films from chloroform solution were 6.0–6.7 kg/mm 2 . And TGA data revealed 10% weight losses and residual weights at 800°C were 437–495°C and 27–40% under nitrogen atmosphere, respectively. © 1992 John Wiley & Sons, Inc.
