Patent number: 6864336Abstract: The present invention is based on quad-fluoropolymer suitable for the preparation of a fluoroelastomer. The fluoropolymer comprises repeating units derived from 10 to 40 mol % of tetrafluoroethylene, 40 to 65 mol % of vinylidene fluoride, 1 to 30 mol % of a perfluorinated vinyl ether of the formula CF2?CFOCF2CF2CF2OCF3, 1 to 20 mol % of perfluoromethyl vinylether.Type: GrantFiled: September 11, 2003Date of Patent: March 8, 2005Assignee: 3M Innovative Properties CompanyInventors: Harald Kaspar, Klaus Hintzer, Guy van Gool, Franz März, Allan T. Worm, Tatsuo Fukushi

Patent number: 6812310Abstract: A fluoropolymer having a reduced amount of polar end groups. The fluoropolymer is produced by free radical polymerization of fluorinated monomers and the initiation of the polymerization is carried out in the presence of a chloride salt. Polar end groups include hydroxy groups and ionized or ionizable end groups. Examples of ionized or ionizable end groups include acid groups and salts thereof such as sulfonic acid and salts thereof, —CH2—OSO3H groups, sulfates and carbonyl containing end groups such as carboxylic and carboxylate groups. Due to the presence of chloride salt at the initiation of the free radical polymerization, CF2Cl end groups are formed instead of the polar end groups. As a result, a fluoropolymer is obtained that has improved processibility and heat resistance.Type: GrantFiled: June 2, 2003Date of Patent: November 2, 2004Assignee: 3M Innovative Properties CompanyInventors: Werner M.
