Publication number: 20030171515Abstract: A method of making a copolymer composition containing a copolymer, which includes the steps of (a) providing a donor monomer composition that includes an isobutylene type monomer; (b) mixing the donor monomer composition with an ethylenically unsaturated monomer composition that includes one or more ethylenically unsaturated acceptor monomers, and is substantially free of maleate type monomers and fumarate type monomers, and (c) polymerizing the mixture resulting from step (b) in the presence of a free radical polymerization initiator. The polymerization is carried out in the substantial absence of Lewis acids and/or transition metals. The isobutylene type monomer is present at a molar excess of at least 10 mol % based on the molar concentration of monomers in the ethylenically unsaturated monomer composition. The ethylenically unsaturated acceptor monomers are present in an amount of at least 15 mol % of the total monomer composition.Type: ApplicationFiled: February 15, 2002Publication date: September 11, 2003Inventors: Simion Coca, Edward R. Coleridge, Gregory J. McCollum, James B. O'Dwyer, James E. Poole, Victoria A. Trettel

Publication number: 20030148158Abstract: The present invention describes the synthesis of new sulforated fluorinated elastomers having very low glass transition temperatures (Tg), a good resistance to bases, oils and fuels and good properties of workability. These elastomers contain, by way of example, from 80 to 60 mole % of vinylidene fluoride (VDF) and 20 to 40 mole % of perfluoro(4-methyl-3,6-dioxaoct-7-ene) sulfonyl fluoride (PFSO2F). In this case, they are prepared by radical copolymerisation of VDF and PFSO2F in the presence of different organic initiators, for example, peroxides, peresters or diazo compounds.Type: ApplicationFiled: November 20, 2002Publication date: August 7, 2003Inventors: Bruno Michel Ameduri, Michel Armand, Mario Boucher, Abdellatif Manseri
