Patent number: 5453477Abstract: Process for the production of PCTFE homopolymer and/or copolymer resins by the use of an aqueous suspension system incorporating a redox initiator system which comprises t-butyl hydroperoxide and sodium metabisulfite to initiate the polymerization or copolymerization process. The process parameters may be controlled to provide a PCTFE homopolymer or copolymer resin having a desired target range of molecular weights. The process provides stable PCTFE polymer suspensions which exhibit a low tendency to coagulate and further exhibit good wettability of the homopolymer and copolymer particles, notably in the absence of soaps.Type: GrantFiled: March 7, 1994Date of Patent: September 26, 1995Assignee: AlliedSignal Inc.Inventors: Bryce C.

Patent number: 4414277Abstract: A process for the production of oligomeric mixtures useful as surfactants is disclosed. The initial step of the process comprises reacting pyromellitic dianhydride with a fluoroalcohol using a mole ratio of about one mole pyromellitic dianhydride per two moles of fluoroalcohol to produce an intermediate which contains two fluorinated ester moieties and two free acid moieties. Thereafter, the intermediate diester-diacid is reacted with an excess of an oxirane compound such as epichlorohydrin, epibromohydrin or propylene oxide wherein said oxirane compound reacts with the free acid moieties to produce ester moieties containing a primary or secondary alcohol moiety. In the final step of the process, additional pyromellitic dianhydride is added to the reaction mixture so that the alcohol moieties may react with anhydride moieties to produce ester linking groups (between pyromellitate nuclei) and additional free acid moieties capable of reacting with the oxirane compound.Type: GrantFiled: August 30, 1982Date of Patent: November 8, 1983Assignee: Allied CorporationInventor: Bryce C.
