ABSTRACT:
Novel polyestercarbonate polymers contain moieties derived from hydroxyaryl-substituted 1,6-diaza [4.4] spirodilactam alternating with moieties derived from a bisphenol haloformate or an aromatic dicarboxylic acid halide, the linking moieties being oxycarbonyl or carbonyldioxy, respectively. The polymers are thermoplastics of relatively high melting points or glass transition temperatures, useful as engineering thermoplastics in elevated temperature applications.
