Class Information
Number: 521/186
Name: Synthetic resins or natural rubbers -- part of the class 520 series > Synthetic resins (class 520, subclass 1) > Cellular products or processes of preparing a cellular product, e.g., foams, pores, channels, etc. > Cellular product derived from reactant which is an aldehyde or aldehyde derivative
Description: Subject matter involving a cellular polymer derived from at least one aldehyde or derivative as a reactant or processes of preparing; composition containing a polymer derived from an aldehyde or derivative as a reactant or involving a polymerizable aldehyde or derivative and which composition is capable of forming a cellular product or processes of preparing; processes of treating a cellular polymer derived from an aldehyde or derivative with a material which neither reacts with the cellular polymer to change or modify chemical bonds therein or neither forms a desired composition with the cellular polymer or products of such a treatment; processes of treating a cellular polymer without the addition of a material whereby a physical or chemical change in the polymer may be effected or products which are the result of such a treatment.
