Publication number: 20020028857Abstract: The present invention relates to thermoplastic compositions which are degradable and/or compostable, the method of preparation of the degradable and/or compostable compositions and use of the degradable and/or compostable compositions in a monofilament, shaped article or film, or may be used as a coating, e.g., of paper, to achieve a stronger article.

Patent number: 5457144Abstract: This invention provides hydrolytically labile polyamide compositions and articles containing an ester derived moiety in the polymer backbone which will degrade after exposure to water over long periods of time.Type: GrantFiled: February 2, 1994Date of Patent: October 10, 1995Assignee: Rohm and Haas CompanyInventors: Norman L. Holy, Newman M. Bortnick
-
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

Patent number: 4288369Abstract: A process for the preparation of cyclic ethers which comprises reacting an alkanediol in which the hydroxyl groups are separated by a chain of at least four carbon atoms in the liquid phase of a catalyst comprising a palladium salt and a copper salt, and recovering the cyclic ether thus formed by a separation step such as distillation. The reaction is carried out in a molecular oxygen gaseous atmosphere. A preferred catalyst is palladium chloride in combination with a copper salt such as cupric chloride or cupric nitrate.Type: GrantFiled: August 31, 1979Date of Patent: September 8, 1981Assignee: Western Kentucky UniversityInventors: Norman L. Holy, Theodore E. Nalesnik
