Title (EN) ADHESIVE COMPRISING POLYISOBUTYLENE POLYMER AND STYRENE ISOBUTYLENE BLOCK COPOLYMER
(FR) ADHÉSIF COMPRENANT UN POLYMÈRE DE POLYISOBUTYLÈNE ET UN COPOLYMÈRE SÉQUENCÉ DE STYRÈNE-ISOBUTYLÈNE
Abstract:
(EN) In one embodiment, an adhesive composition is described comprising a polyisobutylene polymer component, a styrene-isobutylene block copolymer, and optionally a tackifier. The polyisobutylene polymer component comprises one or more polyisobutylene polymers. The polyisobutylene polymer component has an average weight average molecular weight ranging from 15,000 g/mole to 300,000 g/mole. The weight ratio of block copolymer to polyisobutylene polymer of the adhesive composition is greater than 2.2:1. In some embodiments, the adhesive composition is a pressure sensitive adhesive.
(FR) L'invention concerne, dans un mode de réalisation, une composition adhésive comprenant un composant polymère de polyisobutylène, un copolymère séquencé styrène-isobutylène, et éventuellement un tackifiant. Le composant polymère de polyisobutylène comprend un ou plusieurs polymères de polyisobutylène. Le composant polymère de polyisobutylène a un poids moléculaire moyen en poids moyen allant de 15 000 g/mole à 300 000 g/mol. Le rapport en poids du copolymère séquencé au polymère de polyisobutylène de la composition adhésive est supérieur à 2,2:1. Dans certains modes de réalisation, la composition adhésive est un adhésif sensible à la pression.
