| titleOfInvention | Low molecular weight acrylic polymers |
| abstract | 1431446 Low molecular acrylic ester polymers ROHM & HAAS CO 28 March 1973 [5 April 1972] 14886/73 Heading C3P Low molecular weight polymers of one or more esters of acrylic acid are prepared by polymerizing the ester(s) in the presence of an alkoxide as anionic catalyst, whereby the polymer produced has an average chain length of 6 to 30 mers. Suitable esters include those of the formula wherein R is alkyl, cycloalkyl, aminoalkyl, mono- or di-alkylaminoalkyl, heterocyclic-substituted alkyl, alkenyl (e.g. allyl), allyloxyalkyl, alkoxyalkyl, aryloxyalkyl and aralkyl; and also bisacrylate esters of diols. Polymerization is suitably effected by adding the monomer(s) gradually to a suspension or solution of the alkoxide in an inert solvent at a temperature of 20 to 125 C.; an alcohol may optionally be included as a chain regulating agent. The alkoxide catalyst is suitably an alkoxide of sodium or potassium, e.g. sodium methoxide, potassium methoxide or potassium t-butoxide. The ester polymers can be modified by hydrolysis to convert some or all of the ester groups to carboxylic acid (salt) groups. The acid polymers can further be reacted with ethylene or propylene oxide, hydroxyalkyl ester polymers, or with halogenating agents to produce in the latter case acid halide derivatives The ester polymers can also be modified by transesterification with an alcohol; where a polyol, e.g. diol, is used, the modified polymer contains free hydroxyl groups and can be further modified by reaction with a polyisocyanate to form a polyurethane. By virtue of the double bond present at the end of the polymer molecule, the ester polymers can also be copolymerized with other ethylenically unsaturated compounds. The ester polymers and their modified derivatives can be used in such applications as adhesives, plasticizers, levelling agents, meltindex improvers, impregnants, fillers, and in formulating coating compositions; they may be admixed with such components as plasticizers and carriers (diluents). |
