  • Cold flow resistant compositions containing rubber and a block copolymer
    Patent number: 9469752
    Abstract: Disclosed are cold flow resistant and dimensionally stable compositions containing a diene rubber and a conjugated diene monovinylarene block copolymer, and generally, these compositions have solutions viscosities and cold flows that are less than that of the diene rubber. Methods for reducing cold flow and for storage-stabilizing bales of diene rubbers also are disclosed.
    Type: Grant
    Filed: December 8, 2014
    Date of Patent: October 18, 2016
