ABSTRACT:
Novel polyarylate polymers comprise alternating moieties derived from an aromatic dicarboxylic acid halide, with moieties derived from a hydroxyaryl-substituted 1,6-diaza [4.4] spirodilactam compound and, optionally, with moieties derived from a di(hydroxyphenyl) compound. The polyarylate polymers are thermoplastic polymers characterized by relatively high glass transition temperatures.
