Patent number: 4357435Abstract: 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 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.Type: GrantFiled: September 29, 1977Date of Patent: November 2, 1982Assignee: Rohm and Haas CompanyInventors: Sheldon N.

Patent number: 4168255Abstract: This invention discloses the composition and use of salts of low molecular weight polymers of methacrylic and acrylic esters formulated with wetting, emulsifying, plasticizing or coalescing agents as aqueous finish compositions for hard surfaces. The polymers have molecular weights between 700 and 5000 and acid numbers between 50 and 275. The finishes produced by the compositions are water clear and are self-dispersible. Thus, on reapplication, the previous film is dissolved, the embedded soil removed and a fresh film left.Type: GrantFiled: April 13, 1976Date of Patent: September 18, 1979Assignee: Rohm and Haas CompanyInventors: Sheldon N.
