Pressure sensitive adhesive compositions
摘要:
This invention relates to pressure sensitive adhesive compositions which includes a hydrogenated block copolymer such as Kraton G, about 25 to about 250 parts by weight of a hydrocarbon resin of a petroleum or coal tar distillate, aliphatic dienes and mono- and diolefins, cyclic olefins of 5 or 6 carbon atoms and hydrogenated poly cyclics per 100 parts by weight of the hydrogenated block copolymer, and about 25 to 200 parts by weight of a polybutene or polyisobutylene per 100 parts of the hydrogenated block copolymer, wherein said mixture of Kraton G, said hydrocarbon resin and said polybutene or polyisobutylene are dissolved in a non-reactive solvent at a concentration level of about 5 to about 25 grams per 100 mil of non-reactive solvent.
