    摘要: The present invention is at least a two-component thermoplastic elastomeric composition comprising at least one block copolymer wherein the composition has essentially the same comparative elasticity, high temperature serviceability and hardness as the unmodified, undiluted (neat) block copolymer portion of the composition. The composition also shows enhanced thermal stability and processibility and is well suited for fabricating elastic moldings, films and fibers as well as for formulating with asphalts, adhesives and sealants. The novel thermoplastic elastomeric composition comprises (a) from about 50 to about 99 percent by weight of at least one block copolymer and (b) about 1 to about 50 percent by weight of at least one ethylene interpolymer having a density from about 0.855 g/cc to about 0.905 g/cc, wherein the ethylene interpolymer in the amount employed is a substantially inert extender of the block copolymer and the composition is further characterized as having:i. storage moduli throughout the range of -26° C. to 24° C. of less than about 3.5x109 dynes/cm2,ii. a ratio of storage modulus at -26° C. to storage modulus at 24° C. of less than about 4, andiii. storage moduli at -26° C. and 24° C. about 0.2 to about 3 times higher than the storage moduli at -26° C. and 24° C., respectively, of the neat block copolymer portion of the composition.

    摘要: The invention includes a water-curable azidosilane grafted polymer selected from the group consisting of (i) homogeneous ethylene polymers which has a density less than or equal to 0.900 g/cm3, and (ii) interpolymers of at least one ethylene or α-olefin and at least one vinylidene aromatic compound. The water-curable silane-grafted polymer may comprise the reaction product of: at least one first polymer, the first polymer selected from the group consisting of an interpolymer, a substantially linear ethylene polymer, and a mixture thereof; the interpolymer comprising polymer units of at least one ethylene or α-olefin and at least one vinylidene aromatic compound; and at least one monofunctional azidosilane. The invention further includes a process for producing a water-curable silane-grafted polymer. A further embodiment of the process of the invention comprises shaping the water-curable silane-grafted polymer and contacting the shaped water curable silane-grafted polymer to form a moisture-cured polymer. The invention also includes the water curable silane-grafted polymers produced by either of the two processes along with any articles obtainable from that water curable silane-grafted polymer.

    摘要: The invention includes a process of preparing a coupled polymer comprising heating an admixture containing (1) at least one interpolymer of an alpha-olefin and vinyl aromatic monomer and (2) a coupling amount of at least one poly(sulfonyl azide) to at least the decomposition temperature of the poly(sulfonyl azide) for a period sufficient for decomposition of at least 80 weight percent of the poly(sulfonyl azide) and sufficient to result in a coupled polymer. The polymer preferably comprises ethylene, and a vinyl aromatic monomer, preferably styrene. The amount of poly(sulfonyl azide) is preferably from 0.01 to 1 weight percent of the interpolymer and the reaction preferably takes place at a temperature greater than 150 °C, more preferably 185 °C. The process optionally and in one preferred embodiment additionally comprises steps (b) fabricating an article from the coupled polymer and (c) cross-linking the fabricated coupled polymer. The invention additionally includes any composition produced by a process of the invention and any article made from the composition, preferably articles formed from a melt of the composition, more preferably by blow molding, blowing a film, foaming, or profile extruding, most preferably to form a coating for wire or cable, a tube, a gasket, a seal, roofing, or fiber. The article is optionally calendared. Additionally, the invention includes the use of compositions of the invention as starting materials for forming processes in which the composition is melted and especially in blow molding, blowing a film, foaming, or profile extruding, most preferably to form a coating for wire or cable, a tube, a gasket, a seal, roofing, or fiber.
