ADHESIVE COMPOSITIONS

摘要

Hot melt adhesive compositions which include a hydrogenated block copolymer such as Kraton G, about 25 to about 250 parts by weight of a hydrocarbon resin made from a petroleum or coal tar distillate, aliphatic dienes and mono and diolefins, cyclic olefins of 5 to 6 carbon atoms and hydrogenated polycyclics per 100 parts by weight of the hydrogenated block copolymer, and about 25 to about 200 parts by weight of a polybutene or polyisobutylene per 100 parts of the hydrogenated block copolymer. Pressure sensitive adhesive compositions may be prepared by dissolving such mixture of ingredients in a non-reactive solvent at a concentration level of about 5 to about 25 grams 100 ml of non-reactive solvent.
