  • Patent number: 6867265
    Abstract: Rubbery polymers made by anionic polymerization can be coupled with tin halides or silicon halides to improve the characteristics of the rubber for use in some applications, such as tire treads. In cases where the rubbery polymer was synthesized utilizing a polar modifier it is difficult to attain a high level of coupling. This invention is based upon the unexpected finding that coupling efficiency can be significantly improved by conducting the coupling reaction in the presence of a lithium salt of a saturated aliphatic alcohol, such as lithium t-amylate. This invention discloses a process for coupling a living rubbery polymer that comprises reacting the living rubbery polymer with coupling agent selected from the group consisting of tin halides and silicon halides in the presence of a lithium salt of a saturated aliphatic alcohol.

  • Patent number: 4389514
    Abstract: A method of increasing the reaction rate of the polymerization and/or cross-linking of reactive polymerizable and/or cross-linkable acrylic monomeric materials initiated by dialkyl or diaralkyl peroxides as the free radical generator which comprises carrying out such a polymerization and/or cross-linking reaction in the presence of a member of the group consisting of stannous alkanoates, alkenoates, aralkanoates and aralkenoates, dialkyl tin dialkanoates, dialkenoates, diaralkanoates and diaralkenoates, or mixtures thereof in various proportions.

  • Patent number: 4334043
    Abstract: Crosslinkable polymers and co-polymers are treated with organo-metallic compounds, inorganic metallic salts, or lanthanides prior to crosslinking with free radical organic peroxide initiators in the presence of oxygen. This pre-treatment eliminates tackiness of the surface of the crosslinked polymer making the crosslinked polymer more commercially acceptable.

  • Patent number: 4226958
    Abstract: A process is described for the preparation of a polymer having a recurring unit of the formula: ##STR1## where R is hydrogen or methyl, C.sub.n H.sub.2n is lower-alkylene, R.sub.1 and R.sub.2 are aryl or lower-alkyl, and x is 0 or 1. A polymer having a recurring unit of the formula: ##STR2## where X is chloro, bromo, iodo, chloroalkyl, bromoalkyl or iodoalkyl, is reacted with the appropriate aryl or alkyl chloride or bromide and arsenic trichloride, arsenic tribromide or arsenic trioxide in the presence of sodium, magnesium, or lithium metal. The resulting polymer is an intermediate in the preparation, by oxidation, of the corresponding As-oxide which polymer is useful as a catalyst for the conversion of isocyanates to the corresponding carbodiimides.

    Abstract: A process is described for the preparation of a polymer having a recurring unit of the formula: ##STR1## where R is hydrogen or methyl, C.sub.n H.sub.2n is lower-alkylene, R.sub.1 and R.sub.2 are aryl and x is 0 or 1. A polymer having a recurring unit of the formula: ##STR2## where X is chloro, bromo, iodo, chloroalkyl, bromoalkyl or iodoalkyl, is reacted with a triarylarsine in the presence of lithium or sodium-potassium alloy. The resulting polymer is an intermediate in the preparation, by oxidation, of the corresponding As-oxide. The latter is useful as a catalyst for the conversion of isocyanates to the corresponding carbodiimides.

  • Patent number: 4197220
    Abstract: Amine containing polymeric microspheres such as polyvinyl pyridine are complexed with metal salts or acids containing metals such as gold, platinum or iron. After reduction with sodium borohydride, the salt is reduced to finely divided free metal or metal oxides, useful as catalysts. Microspheres containing covalent bonding sites can be used for labeling or separating proteins.
