ABSTRACT:
Disclosed are processes for preparing modifiable poly(aralkyl ketone)s having active methylene group(s) in the main chain comprising reacting an aralkanoic acid or mixtures thereof in the presence of one alkane or aryl sulfonic acid and a condensing agent. Also disclosed are novel modifiable poly(aralkyl ketone)s obtainable by the processes of the inventions.
