    摘要: Disclosed are bituminous blends having improved toughness and elasticity. The blends contain a bituminous binder and a tapered block copolymer formed from a monovinyl aromatic compound and a conjugated diene. Suitable tapered block copolymers include a tapered A-B-A type block copolymer of the A-t-B-t-A configuration, particularly those having an isolated monovinyl aromatic compound content of about 20 to about 90 weight percent, and tapered A-B-A type block copolymers of the A-B-t-A configuration having an isolated monovinyl aromatic compound content of about 20 to about 90 weight percent of the total monovinyl aromatic compound in the tapered block copolymer. Further disclosed is a method of making the blends. Further disclosed is a tapered A-B-A type block copolymer having an isolated monovinyl aromatic compound content of about 29 to about 75 weight percent.

    摘要: The invention is a process for the preparation of storage stable asphalt-polymer blends, comprising: a. contacting sulfur with asphalt; and b. contacting a polymer with the sulfur-asphalt mixture under conditions such that a compatible and homogeneous polymer-asphalt blend is formed. The process of the invention allows the preparation of compatible asphalt-polymer blends that are more stable while utilizing a more cost efficient, faster process and still maintaining the desired physical properties of good weatherability and creep resistance.

    摘要: The invention is a die attach adhesive composition comprising a homogeneous blend of an organopolysiloxane-bridged bisbenzocyclobutene monomer, an organosilane adhesion aid, and a finely divided electrically conductive metal. The composition is easy to apply, exhibits good adhesive strength and thermal stability at high temperatures, and does not require solvents, initiators, or curing agents. Weight loss on cure is minimal.
