Title (EN) SELF-PHOTOINITIATING MULTIFUNCTIONAL URETHANE OLIGOMERS CONTAINING PENDANT ACRYLATE GROUPS
(FR) OLIGOMERES URETHANES MULTIFONCTIONNELS A PHOTOINITIATION SPONTANEE RENFERMANT DES GROUPES D'ACRYLATE PENDANTS
Abstract:
(EN) The present invention relates to self-photoinitiating multifunctional urethane acrylate compositions. More particularly, the present invention relates to liquid oligomeric multifunctional acrylate compositions having pendant acrylate groups and tertiary amine groups bound as part of the polymer structure. The compositions of the present invention cure upon exposure to active radiation such as UV light in the absence of an added photoinitiator. Films made from the crosslinked oligomers of the invention are used as protective or decorative coatings on various substrates. These oligomers can be added to other resins used in adhesives or composites.
(FR) L'invention concerne des compositions d'acrylate d'uréthane multifonctionnel à photoinitiation spontanée. Plus particulièrement, l'invention concerne des compositions d'acrylate multifonctionnel d'oligomères liquides possédant des groupes d'acrylate pendants et des groupes amines tertiaires faisant partie de la structure polymère. Les compositions de l'invention durcissent lorsqu'elles sont exposées à un rayonnement actif de type lumière UV, en l'absence de l'adjonction d'un photoinitiateur. On utilise des films fabriqués à partir de ces polymères réticulés comme revêtement de protection ou de décoration sur différents substrats. Ces oligomères peuvent être ajoutés à d'autres résines utilisées dans des adhésifs ou des composites.
