Class Information
Number: 521/88
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. > Process of forming a cellular product subsequent to solid polymer formation in the presence of a stated ingredient, noncellular composition capable of forming a cellular product and containing a stated ingredient, or process of preparing same > Ingredient is ether, alcohol, or inorganic alcoholate, e.g., phenol, etc.
Description: Subject matter wherein the stated ingredient contains a -C-O-C- group, a C-OH group (X is an inorganic radical), and wherein none of the carbon atoms which are single bonded to the oxygen atom as enumerated above are double bonded to a chalcogen atom (O, S, Se, or Te) or triple bonded to a nitrogen atom, e.g., epoxy compounds, morpholines, cyclic anhydrides, etc.
