摘要 |
<p>A polymer has at least the following characteristics: (a) a block styrene content containing 4 to 6 styrene units from about 27 to about 50 weight percent based on total styrene content in the polymer; (b) a vinyl content from about 30 to about 80 weight percent based on total amount of polymerized 1,3-butadiene; and (c) a styrene content from about 40 to about 70 weight percent based on total weight of polymer. Processes for the polymerization of such a polymer, compositions containing such a polymer, and articles containing at least one component formed from such a composition are described.</p> |
