SHOE SOLES, COMPOSITIONS, AND METHODS OF MAKING THE SAME

A shoe sole composition and method for making a shoe sole are provided. The shoe sole includes a composition comprising a foamed silane-crosslinked polyolefin elastomer having a density less than 0.50 g/cm3. The shoe sole exhibits a compression set of from about 5.0% to about 20.0%, as measured acco...

Zusammenfassung:	A shoe sole composition and method for making a shoe sole are provided. The shoe sole includes a composition comprising a foamed silane-crosslinked polyolefin elastomer having a density less than 0.50 g/cm3. The shoe sole exhibits a compression set of from about 5.0% to about 20.0%, as measured according to ASTM D 395 (6 hrs @ 50° C.). The foamed silane-crosslinked polyolefin elastomer can be produced from a blend including a first polyolefin having a density less than 0.86 g/cm3, a second polyolefin, having a crystallinity less than 40%, a silane crosslinker, a grafting initiator, a condensation catalyst, and a foaming agent.
