要約
(EN)
A thermosensitive adhesive contains a side chain crystal polymer having a melting point of 20-30°C, and a tackifier. The side chain crystal polymer is obtainable by adding a metal chelate compound in the following amount of addition (A) into the following copolymer, followed by a crosslinking reaction. Adhesive strength is to be deteriorated at a temperature below the melting point. The copolymer is obtainable by polymerizing 25-30 parts by weight of (meth)acrylate having a straight-chain alkyl group having 16 to 22 carbon atoms, 60-65 parts by weight of (meth)acrylate having an alkyl group having 1 to 6 carbon atoms, 1-10 parts by weight of a polar monomer, and 1-10 parts by weight of a reactive fluorine compound. The amount of addition (A) is 3-10 parts by weight with respect to 100 parts by weight of a copolymer.

 La présente invention concerne un adhésif thermosensible contenant : un polymère cristallin à chaîne latérale ayant un point de fusion situé dans la plage allant de 20 à 30 °C, obtenu par ajout d'un composé chélaté métallique dans la quantité d'addition (A) à un copolymère et par réalisation d'une réaction de réticulation ; et un agent donnant du collant ; et la force adhésive de l'adhésif thermosensible diminuant à une température inférieure au point de fusion. Copolymère : un copolymère obtenu par polymérisation de 25 à 30 parties en poids d'un (méth)acrylate comprenant un groupe alkyle à chaîne linéaire en C16 à C22, de 60 à 65 parties en poids d'un (méth)acrylate comprenant un groupe alkyle en C1 à C6, de 1 à 10 parties en poids d'un monomère polaire, et de 1 à 10 parties en poids d'un composé fluoré réactif. Quantité d'addition (A) : de 3 à 10 parties en poids par rapport aux 100 parties en poids du copolymère.
