Method of controlling polymer molecular weight and structure |
摘要 |
This invention concerns the preparation of polymers of low polydispersity and/or controlled molecular weight and architecture employing living free radical polymerization initiated by an alkoxyamine initiator or nitroxide plus, optionally a free radical initiator, the polymer produced thereby; selected nitroxide and alkoxyamine initiators; and a process for making the initiators; the polymeric products being useful in protective coatings.
