    摘要: A process of preparing a diblock/triblock composition in a single reaction vessel includes reacting a first monomer, such as styrene, with a first portion of an anionic catalyst in a suitable solvent to form a first polymer block of the triblock. A second step includes adding a second monomer, such as butadiene (when the first monomer is styrene). This forms a second block of the triblock and a first block of the diblock. A further addition of the first monomer completes the diblock and triblock interpolymers. At least a portion of the diblock and/or triblock interpolymers are functionally terminated with a functional terminating agent, such as cyclohexene oxide or isopropanol, to provide the blocks with a functional group. The functional group and the proportion of the interpolymers functionally terminated are selected to provide desired adhesive properties for a particular application.

    摘要翻译: 在单个反应容器中制备二嵌段/三嵌段组合物的方法包括使第一单体如苯乙烯与阴离子催化剂的第一部分在合适的溶剂中反应以形成三嵌段的第一聚合物嵌段。 第二步包括加入第二单体,如丁二烯(当第一单体是苯乙烯时)。 这形成了三次锁的第二块,并且形成了二块的第一块。 另外加入第一单体可完成二嵌段和三嵌段互聚物。 二嵌段和/或三嵌段互聚物的至少一部分用功能性终止剂如环己烯氧化物或异丙醇在功能上终止,以提供具有官能团的嵌段。 选择官能团和功能性终止的互聚物的比例以为特定应用提供期望的粘合剂性质。

    摘要: A process for interpolymerizing a vinyl aromatic hydrocarbon polymer and a block polymer is disclosed. The process includes the following steps: (a) forming a block polymer precursor of at least one polymeric block containing conjugated diene monomer contributed units in the presence of an anionic initiator and in an inert diluent, the block polymer precursor having living ends; and (b) thereafter adding to the block polymer precursor a charge of a vinyl aromatic hydrocarbon monomer and an additional charge of an anionic initiator to simultaneously form (1) a block polymer having a terminal block formed from the charge of vinyl aromatic hydrocarbon monomer attached to the block polymer precursor and (2) a poly(vinyl aromatic hydrocarbon) polymer interpolymerized with the block polymer. The practice of this process produces a vinyl aromatic hydrocarbon block terminated block polymer, such as SBS, interpolymerized with a polymer formed from vinyl aromatic hydrocarbon monomer, such as polystyrene. The resultant interpolymer has a high Gardner Impact Strength and good processability.

    摘要: A process of preparing a diblock/triblock composition in a single reaction vessel includes reacting a first monomer, such as styrene, with a first portion of an anionic catalyst in a suitable solvent to form a first polymer block of the triblock. A second step includes adding a second portion of the catalyst and a second monomer, such as butadiene (when the first monomer is styrene). A portion of the resulting living diblock polymer is then terminated by addition of a chain transfer agent, which forms a second anionic catalyst in the process. Further sequential additions of the second and first monomers copolymerize with both the remaining living diblock and with the second anionic catalyst to complete the triblock polymer and form a second portion of diblock polymer.

    摘要: A rubber-modified asphalt composition is provided. The asphalt composition includes asphalt, a rubber including at least high vinyl poly(conjugated diene), and at least one phenolic curing resin. The high vinyl poly(conjugated diene) has a vinyl content of at least 35%. The use of phenolic curing agents results in improvements to the softening point of the present asphalt composition while also improving toughness and tenacity.
