ABSTRACT:
A controlled free-radical polymerization process for forming end-functionalized polymers is disclosed, particularly by degenerative iodine transfer. The end-functionalized polymers are characterized by a polydispersity less than 2.5 and a predetermined molecular weight. The end-functionalized polymers are useful as reactive intermediates in condensation polymerization, chain polymerization and heterogeneous polymerization reactions.
