(EN) PRESSURE-SENSITIVE ADHESIVE COMPOSITION HAVING HIGH SHEAR STRENGTH
(FR) COMPOSITION ADHESIVE SENSIBLE A LA PRESSION, A FORTE RESISTANCE AU DECHIREMENT
Abrégé
(EN)
This invention provides a normally tacky pressure-sensitive adhesive composition comprising (1) a radial teleblock copolymer having at least three monoalkenyl arene polymer blocks and a branched elastomeric conjugated diene polymer block, (2) a tackifying resin, and (3) from about 5 to about 20 parts by weight extending oil per 100 parts by weight of radial copolymer. This invention relates to normally tacky pressure-sensitive adhesive compositions, and, more particularly, tapes that utilize such compositions.
(FR)
Composition adhésive sensible à la pression, normalement collante à sec, comprenant (1) un copolymère radial séquencé renfermant au moins trois blocs polymères arène monoalkényle et un bloc polymère diène à conjugaison élastomère, (2) une résine collante sèche, et (3) de cinq à environ 20 parties en poids d'une huile plastifiante secondaire par 100 parties en poids de copolymère radial. Cette invention porte sur des compositions adhésives sensibles à la pression, à collage à sec normal et, plus particulièrement, sur des bandes mettant en ÷uvre de telles compositions.
