A composition comprising or obtained from a reaction mixture comprising:
- a first propylene-based polymer;
- an ethylene/α-olefin multi-block copolymer;
- and
- a cure component comprising:
- (i) a second propylene-based polymer that is different than the first propylene-based polymer, the second propylene based polymer being a propylene/ethylene copolymer consisting of (a) from 60 wt % to less than 100 wt % propylene and (b) ethylene, based on the total weight of the propylene/ethylene copolymer, the propylene/ethylene copolymer having a crystallinity from 1 wt % to 30 wt % and a density from 0.86 g/cc to 0.89 g/cc;
- (ii) a scorch retardant;
- and
- (iii) a crosslinking agent;
- wherein the composition is void of ethylene-propylene-diene monomer (EPDM).
