Abstract
Polymers of esters of acrylic acid having an average chain length of about 6 to about 30 mers are prepared by an anionic polymerization reaction, carried out in the presence of a catalytic amount of an alkoxide anion. These polymers, their hydrolysis products, and their derivatives have a wide variety of applications, including among others use as components in films, coatings, fibers, impregnants, adhesives, and binders, and use as modifiers, plasticizers, melt flow improvers, and leveling agents.
