Title
(EN) PHOTOACTIVATABLE CHAIN TRANSFER AGENTS
(FR) AGENTS PHOTOSENSIBLES DE TRANSFERT DE CHAINE
Abstract
(EN) A photoactivatable reagent useful as a chain transfer reagent for providing a semitelechelic polymer having one or more terminal photoactivatable groups. The reagent provides one or more photoactivatable groups and one or more sulfhydryl (or other chain transfer) groups, the photoactivatable and chain transfer groups optionally being joined together by a spacer group. The reagent can be used to prepare a polymer by serving to initiate the polymerization of ethylenically unsaturated monomers. The reagent itself becomes an integral part of the resultant polymer, thereby providing the polymer with a terminal photoactivatable nature. The method provides a number of benefits, including the ability to provide homogeneous photoactivatable polymer compositions, e.g., in terms of the uniform location of the photogroup(s) on the terminal portion of each polymer molecule and the ability to build a desired nonpolar quality, and in turn improved surfactancy, into otherwise polar polymers.
(FR) Réactif photosensible utile en tant que réactif de transfert de chaîne servant à obtenir un polymère semi-téléchélique possédant un ou plusieurs groupes photosensibles terminaux. Ce réactif permet d'obtenir un ou plusieurs groupes photosensibles et un ou plusieurs groupes sulfhydryle (ou autre groupe de transfert de chaîne), les groupes photosensibles et les groupes de transfert de chaîne étant éventuellement reliés par un groupe espaceur. On peut utiliser ce réactif afin de préparer un polymère, étant donné qu'il sert à déclencher la polymérisation de monomères éthylèniquement insaturés. Ce réactif lui-même devient partie intégrante du polymère obtenu, ce qui confère à ce polymère une nature photosensible terminale. Ce procédé offre de nombreux avantages, y compris celui de permettre d'obtenir des compositions polymères photosensibles homogènes, notamment, en termes d'uniformité de l'emplacement du ou des groupes photosensibles situés sur la partie terminale de chaque molécule de polymère, ainsi que celui d'introduire une qualité non polaire souhaitée et, de ce fait, une qualité tensioactive améliorée, dans des polymères qui, sinon, seraient polaires.
