HIGH STYRENE HIGH VINYL STYRENE-BUTADIENE RUBBER WITH NARROW MOLECULAR WEIGHT DISTRIBUTION AND METHODS FOR PREPARATION THEREOF |
摘要 |
A polymer having at least the following characteristics:
(a) a block styrene content with more than 4 consecutive styrene units from about 40 to about 70 weight percent based on total styrene content in the polymer;
(b) a vinyl content from about 25 to about 80 weight percent based on total amount of polymerized 1,3-diene;
(c) a styrene content from about 20 to about 75 weight percent based on total weight of polymer; and
(d) a molecular weight distribution (Mw/Mn) of 1.5 or less. |
