Patent

CA 2441619

A liquid epoxy-functional acrylic resin is disclosed. The resin comprises 10- 90 wt % of recurring units of an epoxy-functional allylic monomer and 10-90 wt % of an acrylic monomer that has a homopolymer Tg less that 0oC. The epoxy- functional allylic monomer has the general structure (formula), R is hydrogen, a C1-C10 alkyl, or a C6-C12 aryl group; A is an oxyalkylene group; and n, which is an average number of oxyalkylene groups, is within the range of 0 to about 15.

L'invention concerne une résine acrylique à fonction époxy liquide. Cette résine comprend 10-90 % en poids d'unités récurrentes d'un monomère allylique à fonction époxy et 10-90 % en poids d'un monomère acrylique renfermant un homopolymère Tg inférieur à 0¿o?C. Le monomère allylique à fonction époxy comporte une structure générale (formule), R représentant un hydrogène, un alkyle en C¿1?-C¿10?, ou un groupe aryle en C¿6?-C¿12?, A représentant un groupe oxyalkylène, et n, qui est un nombre moyen de groupes oxyalkylène, prenant la valeur d'un nombre compris entre 0 et environ 15.
