Abstract
(EN)
The additive for pressure-sensitive adhesives of the present invention is a copolymer comprising an N-substituted maleimide compound and a carboxylated, ethylenically unsaturated monomer as monomer ingredients. The copolymer may contain the N-substituted maleimide compound in a higher weight proportion than the carboxylated, ethylenically unsaturated monomer. The thermosensitive pressure-sensitive adhesive composition of the present invention comprises the additive for pressure-sensitive adhesives and a polymer including crystalline side chains and shows a reduced adhesive force at temperatures lower than the melting point of the polymer including crystalline side chains.
(FR)
L'additif pour adhésifs sensibles à la pression de la présente invention est un copolymère comprenant un composé maléimide N-substitué et un monomère carboxylé, éthyléniquement insaturé en tant qu'ingrédients monomères. Le copolymère peut contenir le composé maléimide N-substitué dans une proportion pondérale supérieure à celle du monomère carboxylé éthyléniquement insaturé. La composition adhésive sensible à la pression thermosensible de la présente invention comprend l'additif pour adhésifs sensibles à la pression et un polymère à chaînes latérales cristallines et présente une force adhésive réduite à des températures inférieures au point de fusion du polymère à chaînes latérales cristallines.
