DEFINITION

Classification: 524/507

With solid polymer derived from at least one -N=C=X (X is chalcogen) reactant wherein at least one of the reactants forming the solid polymer is saturated; or with SPFI or SICP derived from a -N=C=X reactant wherein at least one of the necessary reactants is saturated:

(under subclass 502) Subject matter wherein in addition to the NRM and solid polymer derived from ethylenic reactants only there is additionally present (a) a solid polymer derived from a saturated -N=C=X (X is chalcogen) reactant, or (b) a solid copolymer derived from a -N=C=X containing reactant wherein at least one of the reactants forming the solid copolymer is saturated, or (c) specified polymer-forming ingredients wherein at least one of the necessary ingredients contains a -N=C=X group and at least one of the necessary polymer-forming ingredients is saturated or a reaction product or condensate thereof, or (d) a specified intermediate condensation product which contains a -N=C=X group.
