DEFINITION

Classification: 525/157

Contacting with an amine, a material containing a N or N (X is chalcogen) reactant and an aldehyde or aldehyde derivative at least one of which is saturated, their condensate or solid polymer thereof:

(under subclass 154) Subject matter wherein the polymer from ethylenic reactants only is contacted with an amine, a material containing a N or N moiety and an aldehyde or aldehyde derivative as reactants, their condensate or solid polymer thereof (X is chalcogen).
