摘要： A pressure-sensitive adhesive comprising 100 parts by weight of an isobutylene polymer having been masticated in an organic solvent with a radical generator and 0.001 to 5 parts by weight of at least one release control agent selected from the group consisting of an alcohol having molecular weight of 90 to 300 and an oxygen atom content of 8.5% or more or a derivative thereof; and a surface protecting material having a pressure-sensitive adhesive layer comprising the adhesive. The adhesive has well-balanced characteristics in initial adhesion, retention of initial adhesion, and weather resistance.

摘要： A pressure-sensitive adhesive comprising 100 parts by weight of an isobutylene polymer having been masticated in an organic solvent with a radical generator and 0.001 to 5 parts by weight of at least one release control agent selected from the group consisting of an alcohol having a molecular weight of 90 to 300 and an oxygen atom content of 8.5% or more or a derivative thereof and a carboxylic acid having a molecular weight of 70 to 400 and an oxygen atom content of 11% or more or a derivative thereof; and a surface protecting material having a pressure-sensitive adhesive layer comprising the adhesive. The adhesive has well-balanced characteristics in initial adhesion, retention of initial adhesion, and weather resistance.
