Abstract
(EN)
The invention provides a polyacrylate obtained by radical polymerization of at least one acrylate monomer (Ac) in the presence of a polymeric photoinitiator. The polymeric photoinitiator is a co-polymer of at least one photoinitiator monomer (A) with at least one monomer (B), and optional additional monomers (C). Rapid polymerization of the acrylate monomer is provided. The invention also provides a method for producing a polyacrylate using the polymeric photoinitiator as described, and the use of a polymeric photoinitiator as a photoinitiator of radical polymerization of acrylate monomers.
(FR)
L'invention concerne un polyacrylate obtenu par polymérisation radicalaire d'au moins un monomère acrylate (Ac) en présence d'un photo-initiateur polymère. Le photo-initiateur polymère est un copolymère d'au moins un monomère photo-initiateur (A) avec au moins un monomère (B), et d'autres monomères optionnels (C). L'invention concerne la polymérisation rapide du monomère d'acrylate. L'invention concerne également un procédé de production d'un polyacrylate au moyen d'un photo-initiateur polymère tel que décrit, et l'utilisation d'un photo-initiateur polymère en tant que photo-initiateur de polymérisation radicalaire de monomères acrylate.
