ABSTRACT:
A less colored .alpha., .beta.-unsaturated carboxylic acid polymer having a relatively small molecular weigth and a sharp molecular weight distribution is produced by supplying an .alpha.,.beta.-unsaturated carboxylic acid monomer and a hydrogensulfite from one side of a reaction column and simultaneously supplying an oxygen-containing gas concurrently with the monomer to the reaction column. The polymer obtained is preferably used as a dispersant and an antiscaling agent.
