ABSTRACT:
Novel poly(amideimide) polymers and a method for the production thereof, which polymers are characterized by moieties of a 1,6-diaza [4.4] spirodilactam and of a bis(maleimide) alternating with the non-amino portion of a primary diamine wherein the amino groups are not located upon adjacent carbon atoms. The polymers are thermoplastic polymers of relatively high glass transition temperature.
