DEFINITION

Classification: 525/471

Solid polymer derived from ketone reactant and wherein none of the reactants forming the solid polymer contains an aldehyde group or is an aldehyde-type reactant or polymer derived therefrom:

(under subclass 50) Subject matter involving processes of mixing a solid polymer derived from a ketone reactant and wherein none of the reactants forming the solid polymer is an aldehyde or aldehyde-type reactant or polymer derived therefrom, with an additional solid polymer, with a chemical treating agent, with specified polymer-forming ingredients, specified intermediate condensation product, or with ethylenic agent; processes of forming or reacting the above mixtures, or products resulting from the above processes.
