Abstract: A foamable formulation composition comprises at least 50 weight percent of an ethylene/α-olefin interpolymer having a Comonomer Distribution Constant in the range of from 15 to 250; a density in the range of from 0.875 to 0.963 g/cm3; a melt index (I2) in a range of from 0.5 to 5 g/10 minutes; and long chain branching frequency in the range of from 0.05 to 3 long chain branches (LCB) per 1000 C; (2) a blowing agent; and (3) a cross link agent. The formulation may be processed to result in a foam having a density ranging from 0.05 to 0.25 g/cm3 and have properties such as split tear, compression set, and/or shrinkage percentage that are improved in comparison with otherwise-identical formulations lacking the identified ethylene/α-olefin interpolymer in comparable amount. These foams may be particularly useful for a variety of applications, including, in particular, footwear applications.

Abstract translation: 可发泡制剂组合物包含至少50重量％的共聚单体分布常数在15至250范围内的乙烯/α-烯烃互聚物; 密度范围为0.875-0.963g / cm3; 熔体指数（I 2）在0.5至5g / 10分钟的范围内; 和长链支化频率范围为0.05〜3条长支链（LCB）/ 1000℃; （2）发泡剂; 和（3）交联剂。 可以处理该制剂以产生具有0.05至0.25g / cm 3的密度的泡沫，并且具有与其它相同配方相比具有改善的特性，例如裂纹撕裂，压缩变形和/或收缩百分比。 乙烯/α-烯烃互聚物。 这些泡沫可能对于各种应用，特别是鞋类应用尤其有用。
