Patent number: 5453476Abstract: An improved process for the free radical copolymerization of a mixture of olefins and a polar monomer is disclosed. The process requires the catalytic isomerization of internally-unsaturated olefins to terminally-unsaturated olefins during the copolymerization reaction. The process results in improved yields in terms of solid product formation and in lower costs than conventional processes. The process is especially useful for the preparation of diisobutylene-maleic anhydride copolymers.Type: GrantFiled: August 23, 1993Date of Patent: September 26, 1995Assignee: Rohm and Haas CompanyInventors: Newman M. Bortnick, Norman L. Holy

Patent number: 5412026Abstract: This invention relates to high temperature aqueous processes for the polymerization of monoethylenically unsaturated carboxylic monomers to produce low molecular weight, water-soluble polymer products useful as detergent additives, scale inhibitors, dispersants and crystal growth modifiers. Suitable monomers include acrylic acid, methacrylic acid, maleic acid, maleic anhydride, crotonic acid, and itaconic acid. The reactions are run at temperatures ranging from about 130.degree. C. to 240.degree. C., preferably from about 140.degree. C. to about 230.degree. C. The process can be continuous, semi-continuous, or batch.Type: GrantFiled: September 16, 1993Date of Patent: May 2, 1995Assignee: Rohm and Haas CompanyInventors: Norman L. Holy, Newman M. Bortnick, Graham Swift, Kathleen A. Hughes
