Abstract:
The present invention is related to a grip composition comprising 5 to 10 wt % of a polymer blend modifier, having a weight average molecular weight of 10,000 to 100,000 g/mole, 65 to 75 wt % of a propylene-based elastomer, having a weight average molecular weight of 100,000 to 300,000 g/mole, and a mineral powder. The polymer blend modifier comprises a first propylene-based polymer and a second propylene-based polymer, where the first and second propylene-based polymers are different and are individually selected from a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin. The composition further comprises 5 to 10 wt % of a propylene polymer, which is a homopolymer of propylene or a copolymer of propylene units with from 0.5 to 4 wt % ethylene or C4 to C10 alpha-olefin comonomer derived units.
