The present disclosure relates to compositions including copolymers, and methods for making compositions. In an embodiment, a composition includes the product of a copolymer comprising at least 50 mol % propylene and at least 1 wt % of at least one of ethylene or a Cto Cα-olefin, based on the total weight of the copolymer; and an organic peroxide. The copolymer has Mw/Mnof from 1 to 5. In an embodiment, a process to form a composition includes introducing a copolymer with an organic peroxide, the copolymer comprising at least 50 mol % propylene and at least 1 wt % of at least one of ethylene or a Cto Cα-olefin, based on the total weight of the copolymer; and obtaining a composition comprising a product of the copolymer and the organic peroxide. The copolymer has Mw/Mnof from 1 to 5.
