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, and their derivatives having condensation-crosslinkable functionality have a wide variety of applications, including use as components in films, coatings, fibers, impregnants, adhesives, printing inks, and binders, and use as modifiers, plasticizers, melt flow improvers, and leveling agents.
