Class Information
Number: 528/155
Name: Synthetic resins or natural rubbers -- part of the class 520 series > Synthetic resins (class 520, subclass 1) > From phenol, phenol ether, or inorganic phenolate > With aldehyde or derivative > Two distinct phenolic reactants or two or more hydroxy groups or phenate groups bonded to nuclear carbon atoms of the same benzene ring
Description: Subject matter wherein an aldehyde (1) is reacted with a phenol containing two distinct (-OH) groups or two distinct (-O-Salt) groups or mixtures of these groups and wherein the two (-OH) groups or two (-O-Salt) groups are bonded to two distinct carbon atoms of the same benzene ring, or (2) is reacted with two or more phenolic compounds to their phenolate salts or mixtures thereof.
