    摘要： A thermoplastic polymer having good tensile strength at elevated temperatures is obtained by modifying a block copolymer composed of a conjugated diene compound and an alkenyl arene compound. The block copolymer is first selectively hydrogenated and thereafter modified by grafting silicon or boron containing functional groups primarily in the alkenyl arene block via metalation. Each silicon containing functional group preferably contains at least two functional groups which allow crosslinking by condensation reactions.

    摘要： A process is disclosed for producing six-armed and eight-armed asymmetric radial block copolymers. The process comprises anionically polymerizing a diene and/or a vinyl aromatic hydrocarbon to create living polydiene and/or vinyl aromatic hydrocarbon arms, sequentially anionically polymerizing a vinyl aromatic hydrocarbon and a diene to create living block copolymer arms and coupling the two sets of arms together in one step with a coupling agent that will couple six or eight arms, wherein the molar ratio of the vinyl aromatic hydrocarbon-diene arms to the polydiene arms is sufficient to produce a statistical blend with less than 5 weight percent homopolydiene.

    摘要： A sealant composition comprising:(a) 100 parts by weight of a silane functionalized polymer component which is prepared by reacting enough silane of the general formula R R'.sub.n SiY.sub.3-n (where n equals 0, 1 or 2 and where R is a non-hydrolyzable organic group which is capable of grafting onto the polymer, R' is a non-hydrolyzable organic group incapable of grafting onto the polymer and Y is a hydrolyzable organic group) with a polymer component to thereby functionalize the polymer component and provide a resultant sealant composition with adhesion which is resistant to deterioration in the presence of water;said polymer component comprising an A'B' block copolymer, a multiblock copolymer having at least two end blocks A and at least one midblock B, or mixtures of an A'B' block copolymer and the multiblock copolymer wherein:the A' and A blocks comprise monoalkenyl arene blocks and the B' and B blocks comprise substantially completely hydrogenated conjugated diene polymer blocks, and the average molecular weight of the A and A' blocks is greater than the minimum molecular weight needed to obtain microphase separation and domain formation of the A and A' blocks, and is less than the maximum molecular weight which would render the polymer incapable of being melt processed;the multiblock copolymer comprises a monoalkenyl arene content no more than a maximum weight percent needed to retain a modulus suitable as a sealant for the resultant composition and no less than a minimum weight percent needed to obtain the desired phase separation and the desired minimum cohesive strength for the resultant composition;(b) an amount of a midblock compatible component wherein said midblock compatible component is at a concentration to maintain the resultant composition in a plyable condition at room temperture and to maintain the glass transition temperature of the resultant composition below 10.degree.
