Class Information
Number: 521/152
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 boron containing reactant
Description: Subject matter involving a cellular polymer derived from at least one reactant which contains a boron atom or process of preparing; composition containing a polymer derived from a reactant containing a boron atom or containing polymerizable reactant containing a boron atom and which composition is capable of preparing a cellular product or processes of preparing same; processes of treating a cellular polymer derived from a boron 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 boron containing polymer 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.
