ABSTRACT:
Novel polyamide polymers incorporating moieties of a [4.4] spirodilactam with spiro ring nitrogens in the 1- and 6- spiro ring positions and moieties of a primary diamine are produced by reaction of the primary diamine and a spirodilactam precursor selected from 4-oxoheptanediotic acid compounds or [4.4] spirodilactones having spiro ring oxygen atoms in the 1- and 6- spiro ring positions.
