| 摘要 |
The present invention relates to a method for the production of a UV-curable acrylic copolymer. The method includes polymerizing a mixture of monomers comprising (i) 40-95 wt% of at least one (meth)acrylate monomer, (ii) 5-60 wt% of at least one copolymerizable monomer, wherein said monomer is selected from those whose homopolymers have a glass transition temperature of higher than - 30 °C, and (iii) optionally 0.5-20 wt% of at least one copolymerizable functional monomer having a functional group selected from the group consisting of a hydroxyl group and a carboxyl group to form an acrylic copolymer. The method includes reacting the acrylic copolymer with at least one type of monomer comprising a UV-curable functional group in the presence of a catalyst to form the UV-curable acrylic copolymer. Also encompassed are UV-curable acrylic copolymers thus formed, adhesive composition comprising the UV-curable acrylic copolymers, methods for manufacturing adhesive sheets comprising the UV-curable acrylic copolymers, and use of the UV-curable acrylic copolymers. |
