Patent number: 4716202Abstract: A process for forming ionomer resins neutralized with aluminum is disclosed. In the process a copolymer containing carboxylic acid groups is melt blended in the absence of water with an aluminum compound of the formula ##STR1## where m is 0-2, n is 1-3 and the mixture treated with a volatile organic acid such as glacial acetic acid to activate the reaction between the acid groups of the copolymer and the aluminum compound. The organic acid is then removed from the copolymer by vaporization. Optionally, a moisture scavenger such as acetic anhydride is used to remove water which is incidentally present or formed by the reaction of the aluminum compound.Type: GrantFiled: August 22, 1986Date of Patent: December 29, 1987Assignee: E. I. Du Pont de Nemours and CompanyInventor: Howard W. Strauss

Patent number: 4713422Abstract: Polymers consisting of (a) vinyl compounds having a 2,2'-bipyridyl side group, (b) vinyl compounds having a radiation-sensitive side group and, if appropriate, (c) olefines which differ from (a) and (b), and their complexes with metal compounds, with the exception of alkali metal and alkaline earth metal compounds. They are suitable for coating substrates and for the preparation of photographic relief images. Complexes with cobalt salts are effective catalysts for the polymerization of acetylene.Type: GrantFiled: July 22, 1986Date of Patent: December 15, 1987Assignee: Ciba-Geigy CorporationInventors: Jurgen Kaschig, Jurgen Finter

Patent number: 4711923Abstract: A polymerization process, especially a solution polymerization process, for the preparation of high molecular weight polymers of alpha-olefins less susceptible to yellowness is disclosed. The process comprises feeding monomer(s), coordination catalyst and optionally inert hydrocarbon solvent to a reactor, polymerizing the monomers at a temperature of up to 320.degree. C. and deactivating the catalyst. An organozirconium compound is admixed with the polymer thus obtained. The organozirconium compound is of the formula ZrO.sub.m (OCOR').sub.n (OR").sub.p-n where R' and R" are independently selected from the group consisting of alkyl and cycloalkyl having 1-20 carbon atoms, and m=0 or 1, provided that when m=0, p is 4 and n is 0-4, and when m=1, p is 2 and n=0-2. Any hydrocarbon solvent and other volatile matter are then separated and a composition comprising said high molecular weight polymer is recovered.Type: GrantFiled: December 31, 1986Date of Patent: December 8, 1987Assignee: Du Pont Canada Inc.Inventor: Vaclav G. Zboril
