  • Patent number: 5342896
    Abstract: The subject invention relates to comb polymers having a halobutyl rubber backbone and to techniques for synthesizing such polymers. The comb polymers of this invention can be thermoplastic elastomers. For instance, halobutyl rubbers having sidechains which are derived from vinyl aromatic monomers are thermoplastic elastomers which can be made by a technique of the subject invention. Such thermoplastic elastomers typically have a chlorobutyl rubber backbone and side chains which are comprised of polystyrene. The subject invention more specifically discloses a process for grafting a lithium terminated vinyl aromatic polymer onto a halobutyl rubber which comprises: (1) capping the lithium terminated vinyl aromatic polymer with a diene monomer to produce a lithium terminated diene capped vinyl aromatic polymer, and (2) reacting the lithium terminated diene capped vinyl aromatic polymer with the halobutyl rubber to produce a halobutyl rubber having vinyl aromatic sidechains grafted thereto.

  • Patent number: 5218020
    Abstract: The invention relates to elastomers and articles reinforced with 5 to 30 phr Chitosan particles having a diameter of 0.5 to 75 microns. In an illustrated embodiment, the Chitosan may be modified with an oxygen reactive group or a nitrogen reactive group to make the Chitosan more reactive with an elastomer. Also provided is an economical method of incorporating very fine Chitosan particles into an elastomer matrix. In the method Chitosan is dissolved in an acid and mixed with a coagulating liquid (for coagulating latex), and the mixture of chitosan/coagulating liquid is mixed with a latex solution to provide an elastomer/chitosan composite. The elastomer/chitosan composite may be used as formed or it can be used as a masterbatch and mixed with more elastomer.

  • Patent number: 5206289
    Abstract: The present invention relates to a rubber stock containing 0.1 to 10.0 phr of a polyhydric phenoxy resin. The polyhydric phenoxy resins may be used as a replacement for resorcinol and function as a methylene acceptor. The rubber stocks of the present invention exhibit improved tensile strength at break without the inherent fuming problems associated with resorcinol containing rubber stocks. These beneficial properties are obtained while maintaining high low strain stiffness and cord adhesion associated with resorcinol containing stocks.

  • Patent number: 5202384
    Abstract: It is often desirable to increase the modulus of rubbers utilized in a wide variety of applications. This invention discloses a technique for modifying rubbers to improve their modulus without sacrificing other properties. By utilizing the process of this invention, rubber compositions having increased modulus are prepared by grafting polyester onto rubber. This can be accomplished by reacting a polydiene rubber with a thioacid or maleic anhydride and subsequently with the polyester. It is also possible to prepare such polyester modified rubber compositions by reacting an epoxidized rubber with the polyester.
