Abstract
The present invention is to address the problem of providing an electrically peelable adhesive product having excellent electric peelability even when being exposed to high temperature conditions over a long period of time. The problem is solved by an electrically peelable adhesive composition, comprising an acrylic polymer, an ionic liquid and a highly water-absorbing polymer.
Claims18
An electrically peelable adhesive composition comprising an acrylic polymer, an ionic liquid, a highly water-absorbing polymer, and a migration accelerator, wherein the highly water-absorbing polymer is selected from sodium poly(meth)acrylate, potassium poly(meth)acrylate, ammonium poly(meth)acrylate, calcium poly(meth)acrylate, magnesium poly(meth)acrylate, hydroxyethylecellulose, hydroxypropylcellulose, poly(meth)acrylamide, poly-N-isopropylamide, polyvinylpyrrolidone, polyvinyl acetate, polyvinyl alcohol, polyvinyl butyral, and cross-linking products thereof, wherein the migration accelerator is a polyethylene glycol or an alkyl ether of a polyethylene glycol, and has a weight average molecular weight of 120 to 400.
