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.
