    • 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.
    • 本发明是至少一种包含至少一种嵌段共聚物的双组分热塑性弹性体组合物,其中组合物与组合物未未改性的未稀释(纯)嵌段共聚物部分具有基本上相同的比较弹性,高温可使用性和硬度。 该组合物还显示出增强的热稳定性和加工性,并且非常适用于制造弹性模制品,薄膜和纤维,以及用沥青,粘合剂和密封剂配制。 新型热塑性弹性体组合物包含(a)约50至约99重量%的至少一种嵌段共聚物和(b)约1至约50重量%的至少一种乙烯互聚物,其密度约为0.855克/ cc至约0.905g / cc,其中所用量的乙烯互聚物是嵌段共聚物的基本惰性的增量剂,组合物进一步表征为具有: 在-26℃至24℃的范围内的储存模量小于约3.5×10 9达因/厘米2,ii。 在-26℃下的储能模量与24℃下的储能模量的比小于约4,和iii。 在-26℃和24℃下的储存模量分别比组合物的纯嵌段共聚物部分的-26℃和24℃下的储存模量高约0.2至约3倍。
