Title
(EN) POLISHING CLOTH AND METHOD FOR ATTACHING/DETACHING THE POLISHING CLOTH TO/FROM POLISHING MACHINE BASE PLATE
(FR) TISSU DE POLISSAGE ET PROCEDE POUR ATTACHER/DETACHER LE TISSU DE POLISSAGE SUR/DE LA PLAQUE DE BASE D'UNE MACHINE DE POLISSAGE
Abstract
(EN)
A polishing cloth includes: a polishing cloth substrate; a first pressure-sensitive adhesive layer formed on a back face of the polishing cloth substrate; a support formed on a back face of the first pressure-sensitive adhesive layer; a second pressure-sensitive adhesive layer formed on a back face of the support; and a release sheet releasably attached to the second pressure-sensitive adhesive layer. The second pressure-sensitive adhesive layer includes an adhesive composition. The adhesive composition contains a pressure-sensitive adhesive and a side-chain crystallizable polymer so that the side-chain crystallizable polymer is present in an amount of about 1 % to about 30 % by weight based on the adhesive composition. The side-chain crystallizable polymer includes as a main component thereof an acrylic acid ester and/or methacrylic acid ester which has a straight-chain alkyl group including 16 or more carbon atoms as a side chain.

Un tissu de polissage comprend: un substrat de tissu de polissage; une première couche autocollante formée sur une face arrière du substrat de tissu de polissage; un support formé sur une face arrière de la première couche autocollante; une seconde couche autocollante formée sur une face arrière du support; et une feuille de décollement fixée amovible à la seconde couche autocollante. La seconde couche autocollante comprend une composition adhésive. La -composition adhésive contient un autocollant et un polymère cristallisable à chaîne latérale de manière que le polymère cristallisable à chaîne latérale soit présent en une quantité d'environ 1 % à environ 30 % en poids sur la base de la composition adhésive. Le polymère cristallisable à chaîne latérale comprend comme constituant principal un ester d'acide acrylique et/ou un ester d'acide méthacrylique ayant un groupe alkyle à chaîne alkyle latérale contenant 16 atomes de carbone ou plus en tant que chaîne latérale.
