  • Azide-functionalized polymer and process of making and using thereof
    Patent number: 11613598
    Abstract: 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.
    Type: Grant
