A polymer blend is provided, which includes 100 parts by weight of a first polyolefin, 3 to 100 parts by weight of a thermoplastic polyurethane, and 3 to 10 parts by weight of a modified polyolefin. The modified polyolefin is formed by grafting maleic anhydride or acrylate onto a second polyolefin. The blend can be used to form fiber.

This invention relates to a process for forming an azide-grafted polymer. The process comprises mixing a free-radical-reactive polymer with a free-radical initiator and an azide monomer that contains at least one unsaturated C═C bond capable of reacting with a radical, under solid-state grafting conditions, to form an azide-grafted polymer. The formed azide-grafted polymer can be used to prepare a long-chain branched or cross-linked polymer.
