Abstract
Synthesizing poly(alkoxyamine amide)s, which have a monomer chain with at least one thermolabile bond between monomers from an acid monomer of a monohalogenated carboxylic acid X—C(R,R')—Y—COOH and an amine monomer having a free terminal free-radical nitroxide group >N—Oand a free terminal primary amine —NH. The synthesis involves two separate and chemically selective chemical reactions. One reacts the —COOH and —NHgroups to obtain an amide bond —NH—CO—Y—C(R, R′)—, and the other reacts the —Y—C(R, R′)free-radical with the nitroxide function >N—Oin order to obtain an alkoxyamine bond —Y—C(R, R′)—O—N<. The chemical reactions are performed in alternating fashion with catalysts and a novel halogenated acid monomer X—C(R,R′)—Y—COOH or a novel free-radical amine monomer having a free terminal group >N—Oand a free terminal primary amine —NH, until a complete copolymer chain is obtained. Also the polymers obtained and the uses thereof.
