    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： Compositions exhibiting high catalytic activity in the polymerization of .alpha.-olefins at temperatures above 140.degree. C. are provided by reacting a transition metal compound such as tetra(isopropoxy)titanium, an organomagnesium component such as a hydrocarbon soluble complex of dialkyl magnesium and an alkyl aluminum, e.g., di-n-butylmagnesium.x triethylaluminum and a hydrogen halide or an active hydrocarbyl halide such as t-butyl chloride. Polymerization processes employing this catalyst composition do not require conventional catalyst removal steps in order to provide polymers having suitable color and other physical characteristics.

    摘要： Compositions exhibiting high catalytic activity in the polymerization of .alpha.-olefins, particularly higher olefins, are prepared by reacting tetravalent or trivalent titanium compounds such as a titanium tetralkoxide, an anhydrous nickel compound such as nickel chloride, an organomagnesium component such as a hydrocarbon soluble complex of dialkyl magnesium and an alkyl aluminum and a halide source such as a hydrogen halide or an alkyl aluminum halide. Polymerization processes employing this catalyst composition do not require conventional catalyst removal steps in order to provide polymers having suitable color and other physical characteristics and these catalysts produce polymers having broader molecular weight distributions than do corresponding catalysts without the anhydrous nickel compound.
