Synthesis of high vinyl rubber |
| abstract |
This invention is based upon the discovery that rubbery polymers havingna high vinyl content and a low degree of branching can be synthesized with anninitiator system that is comprised of (a) a lithium initiator selected from the groupnconsisting of allylic lithium compounds and benzylic lithium compounds, (b) anGroup I metal alkoxide, and (c) a polar modifier; wherein the molar ratio of thenGroup I metal alkoxide to the polar modifier is within the range of 0.1:1 to 10:1;nand wherein the molar ratio of the Group I metal alkoxide to the lithium initiatornis within the range of 0.01:1 to 20:1. These high vinyl polymers offer reducednlevels of hysteresis and better functionalization efficiency. By virtue of theirnlower level of hysteresis these polymers can be utilized in manufacturing tirentread compounds that exhibit lower levels of rolling resistance and cannaccordingly be used to improve the fuel economy of motor vehicles withoutncompromising other desirable characteristics, such as traction and tread-wear. |
