| 发明名称 | Cold flow resistant compositions containing rubber and a block copolymer | ||
| 摘要 | 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. | ||

| 主权项 | 1. A cold flow resistant composition comprising: (a) a diene rubber; and (b) a conjugated diene monovinylarene block copolymer, the conjugated diene monovinylarene block copolymer having from about 50 to about 95 wt. % monovinylarene monomer content, based on the total weight of the block copolymer;wherein: a solution viscosity of the composition is less than a solution viscosity of the diene rubber; a cold flow of the composition is less than a cold flow of the diene rubber; the composition contains less than 1 wt. % solvent; and the composition comprises from about 15 to about 30 wt. % of the conjugated diene monovinylarene block copolymer, based on the total weight of the composition. | ||
