摘要： A process is provided to prepare a composition of bitumen, carbon black, and a block copolymer, the block copolymer being a hydrogenated or unhydrogenated block copolymer comprising, before hydrogenation, at least two blocks which comprise predominantly polymerized monoalkenyl arenes and at least one block which comprises predominantly polymerized conjugated diolefins. The process involves blending of the carbon black with the block copolymer and then combining the carbon black-block copolymer mixture with bitumen. The product of the process of this invention has excellent storage stability and aged tensile strength properties, and has superior weatherability.

摘要： A process is provided which produces a waterproof membrane and applies this waterproof membrane directly to a fixed substrate. The process includes the steps of providing a polymeric material; melting the polymeric material; forcing the melted polymeric material through a movable die, the movable die shaping the polymeric material melt into a film; moving the movable die across the fixed substrate; and applying the film directly to the fixed substrate forming a waterproof membrane. The polymeric material is one of those known in the art to be useful as roofing material. In a preferred embodiment, this process produces a sealing membrane which is applied to a roof of a structure forming a membrane effective to protect the structure from intrusion of water. In another aspect, an apparatus is provided which is capable of performing the process of this invention.

摘要： The present invention is a process for producing high diblock content block copolymer compositions which comprises (a) anionically polymerizing at least one vinyl aromatic hydrocarbon and at least one conjugated diene to form a living block copolymer, (b) coupling the block copolymer with a coupling agent selected from the group consisting of esters of carboxylic acids and asymmetric silanes to create a coupled polymer, (c) combining the coupled polymer with other components to form an enduse composition, and (d) heating the composition at a temperature up to 130.degree. C. for a time sufficient to decouple the coupled copolymer such that the amount of uncoupled copolymer in the composition ranges from 10 to 100% by weight of the total amount of block copolymer.
