  • Patent number: 5502131
    Abstract: An anionic polymerization initiator includes the C-lithio reaction product of an organolithium compound and a tertiary-amino allyllithium or a tertiary-amino xylyllithium. When used in an anionic polymerization, a functional group from the initiator is incorporated onto the head of the growing polymer and a lithium atom is incorporated at the "living" end of the polymer chain prior to quenching. The initiator may be used to polymerize a monomer(s) including diolefin monomers, monovinyl aromatic monomers and trienes, and the living ends of the polymers are effectively maintained even at temperatures of up to 300.degree. F. and higher. Such polymers exhibit an increased efficiency in coupling termination reactions, and products prepared from such polymers exhibit improved hysteresis characteristics. Products such as tires and the like can be prepared from such polymers and from vulcanizable elastomer compositions employing the polymers.

  • Patent number: 5340883
    Abstract: Compositions useful as absorbents for organic liquids are disclosed. A diamine or polyamine is reacted with a polymeric resin that contains phosphonic acid groups to produce the absorbent compositions of the invention. Because the polymeric resin component can be combined with the amine either before or after combination with the organic liquid, the absorbents of the invention can be used in many forms. The polymeric resin component can be processed into any desired form (shaped article, solution), and the di- or polyamine can then be added to generate the absorbent in situ. Unlike spent absorbent compositions of the prior art, those of the invention can be converted to pumpable liquids by heating or by adding a gel-breaking agent to liquify the gel. A useful absorbent is recovered from the liquid by precipitation or distillation.

  • Patent number: 5328179
    Abstract: Gasketing paper is commonly made by the beater addition process. In the beater addition process a furnish composition is prepared by mixing latex into a fiber slurry which also typically contains one or more fillers. The beater addition process is currently being scrutinized because of environmental concerns. More specifically, conventional lattices used in the beater addition process contain curatives, such as amines, sulfur, and zinc compounds, which are discharged into the environment via the affluent from the process. By practicing the process of this invention gasketing paper can be manufactured by an environmentally sound technique. In one embodiment of this invention gasketing paper is made by beater addition with the latex utilized in the process being comprised of (a) at least one rubber having both pendant blocked isocyanate groups and groups containing at least one active Zerewitinoff hydrogen, (b) at least one emulsifier, and (c) water.

  • Patent number: 5292813
    Abstract: This invention relates to novel compositions of matter, fullerene graft amine-containing polymers, and the process of making them. The graft is made by reacting a fullerene with a primary or secondary amine-containing polymer, preferably a hydrocarbon containing polymer in effective amounts, typically from about 10:1 to about 1:10 mole ratio of reactive amine in polymer to fullerene for a time and under conditions effective to produce the compositions. Suitable starting polymers are those containing primary or secondary amino groups, e.g., EPDM amine, PIB-amine, PIBSA-PAM, and Mannich based polymers. The preferred polymers are oil soluble, as the novel compositions of that type may be used as viscosity modifiers and lube additives. The crosslinked compositions may be used in essentially any application as the original polymer, but in which an increase in tensile strength would be desired.
