DEFINITION

Classification: 525/480

Solid polymer or specified intermediate condensation product derived from at least one phenolic reactant and at least one aldehyde or aldehyde-type reactant or polymer therefrom:

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

(1) Note. When a nonsolid specified intermediate condensation product is involved, the chemical treating agent must be a solid polymer, a specified intermediate condensation product, or part of a specified polymer-forming ingredient system or be an ethylenic agent.
