  • High modulus rubber composition
    Patent number: 4996263
    Abstract: It is 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. The subject invention more specifically relates to a process for preparing a rubber composition having a high modulus which comprises reacting maleic anhydride with at least one polydiene rubber and at least one nylon.
    Type: Grant
    Filed: October 6, 1988
    Date of Patent: February 26, 1991

  • Polyester reinforced rubber
    Patent number: 4996262
    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.

  • High modulus rubber composition
    Patent number: 4992513
    Abstract: It is 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. The subject invention more specifically relates to a process for preparing a rubber composition having a high modulus which comprises reacting at least one epoxidized rubber with from about 2 phr to about 55 phr of at least one nylon at a temperature which is within the range of about 140.degree. C. to about 300.degree. C.
