Patent number: 8263719Abstract: A polymerization process for producing a tetra-fluoroethylene copolymer, and the copolymer produced thereby, are provided. The copolymer is of the dispersion/fine powder type and contains polymerized tetrafluoroethylene monomer units and co-polymerized higher homologous comonomer units having the formula (CnF(2n+1))CH?CH2, wherein 6?n<10, in which the primary particles are believed to have a core and shell structure and the polymerized comonomer units are present in an amount from 0.01 mol % to 0.3 mol %, based upon total copolymer composition. The copolymer has a raw dispersion primary particle size (RDPS) of less than 0.210 microns coupled with a standard specific gravity (SSG) of less than 2.143. Preferably the copolymer has comonomer units present in an amount from 0.05 mol % and 0.25 mol % and the RDPS is within the range between 0.178 microns and 0.200 microns, coupled with a SSG of less than 2.140.Type: GrantFiled: February 17, 2009Date of Patent: September 11, 2012Assignee: Gore Enterprise Holdings, Inc.Inventors: Edward A. Sabol, Richard L. Baillie

Patent number: 7084225Abstract: A polymerization process for producing a copolymer of tetrafluoroethylene and (perfluorobutyl)ethylene, prepared by an aqueous dispersion polymerization technique, and the resin produced thereby, are provided. This copolymer contains a relatively small amount, between about 0.02 weight percent and about 0.6 weight percent, of comonomer polymerization units. The copolymer is believed to be comprised of a core-shell structure wherein the polymerized comonomer units reside primarily within the core. The primary particle size of the copolymer ranges from 0.175 microns to and including 0.203 microns and the standard specific gravity is less than 2.143. This copolymer possesses a unique combination of very small particle size coupled with high molecular weight, a combination not heretofore achieved in tetra-fluoroethylene polymers of the dispersion or fine powder type.Type: GrantFiled: February 7, 2005Date of Patent: August 1, 2006Assignee: Gore Enterprise Holdings, Inc.Inventor: Richard L. Baillie
