Abstract
PURPOSE: To prepare a pressure-sensitive adhesive having improved cohesive force, bond strength to a polar film, and adhesivity to a polar adherend, by using a graft polymer of a liquid diene rubber and a vinyl monomer (having a functional group), as a main component.
CONSTITUTION: A graft polymer is obtained by grafting 100pts.wt. of a liquid diene rubber (pref. a liquid isoprene rubber having a molecular weight of 1,000W 200,000) with 3W100pts.wt. of a vinyl monomer (e.g. lauroyl methacrylate) and/or a functional vinyl monomer (e.g. acrylic acid) in the presence of a solvent such as toluene (pref. 40W70wt% in concentration). The conversion of the vinyl monomer is ≥60% and the degree of grafting is ≥90%. The graft polymer is used as a component of the objective adhesive. The adhesive is pref. incorporated further with natural rubber, polyisocyanate, and a tackifier resin (e.g. polyterpene resin) to improve the initial tackiness and the adhesivity.
