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.
La présente invention concerne la préparation de polymères à faible polydispersité et/ou à architecture et poids moléculaires contrôlés, par polymérisation radicalaire vivante initiée par un initiateur alkoxyamine ou un nitroxyde et, éventuellement, un initiateur radicalaire. L'invention concerne également le polymère ainsi produit, des initiateurs alkoxyamine et nitroxyde sélectionnés, ainsi qu'un procédé de production des initiateurs, lesdits produits polymères étant utiles dans des enduits protecteurs.
