ABSTRACT:
Polymers of esters of methacrylic acid having an average chain length of about 6 to about 50 mers are prepared by an anionic polymerization reaction, carried out in the presence of a chain-regulating alcohol and a catalytic amount of an alkoxide anion, in which control of the molecular weight and molecular weight distribution of the polymer are achieved by regulating the ratio of the total quantity of alcohol employed to the total monomer charge. These polymers, their hydrolysis products, or their hydroxyl-containing derivatives are esterified or transesterified to give polymers having pendant acrylate or methacrylate functionality which are useful in formulating films, coatings, inks, and the like.
