ABSTRACT:
Novel polymers containing amide moieties are produced by reaction of a spirodilactam precursor selected from 4-oxoheptanedioic acid compounds or 1,6-dioxa [4.4] spirodilactones, a primary diamine and an aromatic, aliphatic or alicyclic dicarboxylic acid compound. The polymer products have relatively high glass transition temperature.
