DEFINITION

Classification: 525/509

Solid polymer or specified intermediate condensation product derived from at least one amine-, N or N- containing reactant and at least one aldehyde or aldehyde-type reactant (X is chalcogen):

(under subclass 50) Subject matter involves processes of mixing a solid polymer or specified intermediate condensation product derived from at least one amine and/N or N- containing reactant and at least one aldehyde or aldehyde-type reactant or polymer thereof with an additional solid polymer, with additional specified intermediate condensation product, with specified polymer-forming ingredients or with ethylenic agent; processes of mixing solid polymer derived from at least one amine and/N or N- containing reactant and at least one aldehyde or aldehyde-type reactant or polymer thereof with a chemical treating agent; or products resulting from the above mixing processes (X is chalcogen).

(1) Note. In this and the indented subclasses, an amine and/N-C- or O N-S-aldehyde, or aldehyde-type condensate must be a solid in order for a mixture thereof and a chemical treating agent to be classified herein.
