    摘要： A method of making a polymer with stable Mooney viscosity and molecular weight is described. A conjugated diolefin is reacted in a hydrocarbon solvent in the presence of an initiator to form a polymer. After forming the polymer, alkoxy silane terminal functionalizing groups are bonded to the polymer. A mixture of at least one of a first stabilizing agent having the formula (R)4-nSi(OH)n wherein R is a C1 to C18 alkyl, C1 to C18 alkyl group containing a heteroatom such as nitrogen or oxygen, C4 to C8 cycloalkyl, or C6 to C18 aromatic group, and a at least one of a second stabilizing agents having the formula (R)2Si(OH)2 wherein R is an aryl group, is then added to the polymer, optionally in the presence of hydrocarbon oil. The polymer is then desolvatized, resulting in a polymer with stable Mooney viscosity and molecular weight, even over prolonged periods of time. Compositions and articles containing the polymer are also described.

    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.
