ABSTRACT:
The present invention relates to polyolefin compositions comprising: (a) 20 to 50 parts by weight of a particular propylene polymer having an MWD greater than 3.5; and (b) 50 to 80 parts by weight of an elastomeric ethylene copoymerR having a low enthalpy of fusion and a narrow MWD. The compositions of the invention are capable of gining, after dynamic vulcanization, thermoplastic elastomeric products having optimum elastomeric properties and a good balance of physico-mechanical properties
