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 3.5×109 dynes/cm2, ii. a ratio of storage modulus at −26° C. to storage modulus at 24° C. of less than about 4, and iii. 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： A process for producing static-free synthetic rubber includes mixing acrylonitrile-butadiene, Anti-static agent, Activated zinc oxide, Zinc stearate, HI-sil (EPDM), Plasticizer, and Stearic Acid prior to a kneading process at 140 degrees Celsius for 8 to 12 minutes. (DCP) Peroxides and Blowing agents are added to the kneeing mixture two minutes before the end of the kneeding process. After the kneeding process, the resultant mixture is fed through rollers to form a sheet of the synthetic rubber. The sheet is then cut into appropriately-sized pieces and put into a mold, where the pieces are subjected to high pressure and a temperature of 160 degrees Celsius. The pieces are then left to cool, and then be used for articles such as static-free footwear.

摘要： A thermoplastic molding composition comprising a grafted rubber and a copolymeric matrix is disclosed. The composition is characterized in that its grafted rubber includes a substrate, a first grafted phase and a subsequent grafted phase which are sequentially grafted to said substrate. The substrate which contains a crosslinked elastomer is grafted with a first grafted phase and with a subsequent grafted phase, both phases containing copolymers of at least one vinylaromatic monomer and at least one member selected from the group consisting of (meth)acrylonitrile and alkyl (meth)acrylate. The relative ratios of the monomers making up the copolymerized phases differ one from the other. The grafted rubber is present in particulate form having a weight average particle size of about 0.1 to 1.0 microns. The composition features improved impact strength and reduced opacity.

摘要： The rubber mixtures containing modified rubber gels according to the invention prepared from at least one rubber gel modified with compounds containing sulphur and reactive towards C═C double bonds and at least one rubber containing double bonds are preferable suitable for the production of vulcanizates which have an unusually strong reinforcing action in rubber vulcanizates. The vulcanisates furthermore exhibit unusually low dynamic damping at relatively elevated temperatures. They are thus particularly suitable for the production of low rolling resistance motor vehicle tire treads.
