  • Patent number: 5003012
    Abstract: The present invention concerns an improved process for producing an ionomer from an acid group containing polymer. Production of the ionomer requires neutralization of an acid functionality or reaction of anhydride functional groups with a metal ion source to produce a salt. It has been found that metal hydrocarbyls or metal hydrides can be used as the source of metal ions for neutralizing the acid or anhydride functionalities. The reaction can occur in a solvent or in a melt, but is most preferably performed in a solvent.

    Abstract: Modified rubber compositions are described which comprise at least one polymer rubber containing carbon-carbon unsaturation, at least one aromatic furazan oxide, and at least one hydrocarbon-soluble transition metal salt. When a transition metal salt is included in such polymer rubber formulations containing aromatic furazan oxides, the undesirable odors which normally characteristic of such rubber formulations is diminished or eliminated without significantly reducing the other desirable characteristics of the vulcanized rubbers. For example, filled vulcanizates made by vulcanizing mixtures in accordance with the invention exhibit high rebound, and tires which are formulated to include at least a portion of the cured vulcanizates in the tread exhibit reduced rolling resistance. Preferably, the hydrocarbon-soluble transition metal salts are the aliphatic or alicyclic monocarboxylic acid salts or cobalt, iron, nickel or manganese.

  • Patent number: 4746687
    Abstract: A new and improved composition and method for profile modification of subterranean formations characterized by high reservoir temperatures and/or harsh brine conditions are disclosed. The new and improved profile modification agents comprise a gelable composition comprising:(a) water;(b) a water-thickening and crosslinkable amount of a water-dispersible copolymer comprising from about 30 to about 99 mol % of units derived from at least one N-sulfohydrocarbon substituted acrylamide monomer copolymerized with from about 1 to about 70 mol % of units derived from at least one other monomer bearing a carboxyl group or a carboxyl precursor group; and(c) an amount of a polyvalent metal sufficient to crosslink the polymer to form a stable gel. The profile modification agents are effective to alter the permeability of preselected portions of an underground formation by forming strong gels which are stable in harsh brine at temperatures of up to about 120.degree. C.

  • Patent number: 4716202
    Abstract: 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.

  • Patent number: 4711923
    Abstract: 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.
