TEMPORARY ATTACHMENT ADHESIVE TAPE FOR MULTILAYER CERAMIC CAPACITOR AND METHOD FOR PRODUCING MULTILAYER CERAMIC CAPACITOR

摘要

A TEMPORARY ATTACHMENT ADHESIVE TAPE FOR A MULTILAYER CERAMIC CAPACITOR INCLUDES A SUBSTRATE FILM AND AN ADHESIVE LAYER PROVIDED ON ONE FACE OR BOTH FACES OF THE SUBSTRATE FILM. THE ADHESIVE LAYER IS FORMED OF A POLYMER COMPOSITION CONTAINING A POLYMER HAVING A FIRST-ORDER MELTING TRANSITION WHICH OCCURS OVER A TEMPERATURE RANGE NARROWER THAN ABOUT ABOUT 15°C. THE POLYMER IS A SIDE-CHAIN CRYSTALLIZABLE POLYMER. THE SIDE-CHAIN CRYSTALLIZABLE POLYMER IS PRESENT IN THE POLYMER COMPOSITION IN AN AMOUNT EFFECTIVE TO RENDER THE POLYMER COMPOSITION SUBSTANTIALLY NONTACKY AT ROOM TEMPERATURE OR LOWER AND TACKY AT TEMPERATURES ABOVE ROOM TEMPERATURE. THE SIDE-CHAIN CRYSTALLIZABLE POLYMER IS A POLYMER MAINLY COMPOSED OF ACRYLATE AND/OR METHACRYLATE HAVING A LINEAR ALKYLGROUP OF 10 OR MORE CARBON ATOMS AS A SIDE-CHAIN.(FIG 1F)
