摘要： The present invention relates to advanced flame/fire retardant compositions for fabric, upholstery, carpet, barrier, automotive, building construction, communication, and consumer electronics applications. The flame retardant composition comprises: about 5-25 wt. % hydrogenated styrenic block copolymer, about 6-40 wt. % polyolefin, about 50-80 wt. % inorganic flame retardant, about 0-5 wt. % coating, about 0-5 wt. % functionalized styrenic block copolymer, about 0-7 wt. % agri-derived heat resistant liquid, about 0.05-1.0 wt. % antioxidant, and about 0-7 wt. % optional additives such as metal deactivator, colorant, filler, and/or lubricants, wherein said composition totals 100 wt. %. An article made from the flame retardant composition, such as film, fiber, cable, and wire insulation meets various European and U.S. standards. The flame retardant compositions possess a good balance of tensile strength, elongation, flame resistance, and processability that has previously been unobtainable.

摘要： A novel process for preparation of block copolymers containing for example, alpha-methyl-styrene / styrene glassy blocks is claimed, where the glassy blocks contain 25 - 50 mol % alpha-methyl-styrene and have Tg values in the range of 120 to 140°C. The copolymerization process, which is conducted at 35 to 60°C and relatively high solids contents and with continuous addition of styrene, results in very high conversions of the alpha-methyl-styrene. Selectively hydrogenated block copolymers having high glassy block Tg values are also disclosed and claimed as well as high service temperature elastomeric compositions comprising the block copolymer and an olefin polymer or copolymer.

摘要： The present invention relates to novel compositions comprising (a) anionic block copolymers of mono alkenyl arenes and conjugated dienes, and (b) tailored softening modifiers have a particular polydispersity index that results in a surprising improvement in properties for the composition. Also included are processes for the manufacturing such novel compositions and various end-uses and applications for such compositions.
