Patent ID: 8314186

Claim:
An adhesive composition prepared from 100 parts by weight of a component (A) and 0.01 to 1 part by weight of a component (B), wherein the component (A) is an acrylic-based polymer graft-polymerized and modified by a reactive silane coupling agent and has a weight-average molecular weight of between 700,000 and 1,200,000, and, according to a total weight of the acrylic-based polymer, the component (A) is synthesized by polymerization of: a. 50˜98% of alkyl group-containing (meth)acrylic acid; b. 1˜10% of hydroxyl group-containing (meth)acrylic acid; c. 0.1˜5% of carboxyl group-containing (meth)acrylic acid; and d. 0.01˜2% of reactive silane coupling agent; and the component (B) is a cross-linking agent.
