摘要:High molecular weight polyarylate polymers comprise alternating moietiesderived from an aromatic dicarboxylic acid halide, with moieties derived from ahydroxyaryl-substituted 1,6-diaza [4.4] spirodilactam compound and, optionally, withmoieties derived from a di(hydroxyphenyl) compound are prepared by interfacialpolymerization in an aqueous-organic medium containing an alcohol.
