DYNAMICALLY VULCANIZABLE POLYOLEFIN COMPOSITIONS

摘要

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 copolymer having a low enthalpy of fusion and a narrow mwd. The compositions of the invention are capable of giving, after dynamic vulcanization, thermoplastic elastomeric products having optimum elastomeric properties and a good balance of physico-mechanical properties.
