Abstract

Polymers containing recurring quinoline or anthrazoline groups which are reaction products of aromatic amino carbonyl compounds containing two sets of ortho-amino aldehyde or ortho-amino ketone functions attached to the aromatic nucleus having the general structure: ##STR1## (wherein R is hydrogen, or aryl and the Ar's are aryl groups) with methylene ketones containing two ketone functions having a methylene group adjacent to each ketone and having the general structure: ##STR2## (wherein R = hydrogen or aryl and R' = aryl and the Ar's are aryl groups) are described. According to the above, R from both the aromatic amino carbonyl and the aromatic methylene ketone could be hydrogen when producing a polymer, but the polymer in which both R's are hydrogen is excluded from this invention.
