Class Information
Number: 521/155
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 a -n=c=x containing reactant wherein x is a chalcogen atom
Description: Subject matter involving a cellular polymer derived form at least one reactant which contains a -N=C=X group (X is a chalcogen)or process of preparing; composition containing a polymer derived from a reactant containing a -N=C=X group or involving a polymerizable reactant containing a -N=C=X (X is a chalcogen)group and which composition is capable of preparing a cellular product or processes of preparing same; processes of treating a cellular polymer derived from a -N=C=X (X is a chalcogen)containing reactant 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 derived from a -N=C=X reactant without the addition of a material thereto whereby a physical or chemical change in the polymer may be effected or products which are the result of such a treatment.
