摘要： PURPOSE: Title adhesives and tape are provided which has a good electric insulating property, thermal resistance and adhesive force. CONSTITUTION: Polyimide resin(formula 1 and 2) is dissolved in organic solvent to give the polyimide adhesives. Thus, benzophenon tetracarboxylic acid-2-anhydride as a tetracarboxylic acid-2-anhydride is dissolved in N-methyl-2-pyrrolidone at 25°C. 0.5 Mole of 4,4'-diaminodiphenyl sulfide and 0.5 mole of 2,2-bis(4-£3-aminophenoxy|phenyl)sulfone are mixed. 0.5 mole of 4,4-diaminodiphenyl sulfide and 0.5 mole of 2,2-bis(4-£4-aminophenoxy|phenyl)sulfone are stirred for 5 hours to give polyamic acid. Obtained 15 weight % of polyamic acid is coated on the polyimide film, and dried at 100°C for 3 minutes, at 130°C for 4 minutes, at 200°C for 3 minutes, and at 300°C for 1 hour to give the title adhesive tape.
摘要翻译：目的：提供标签粘合剂和胶带，具有良好的电绝缘性，耐热性和粘合力。构成：将聚酰亚胺树脂（式1和2）溶解在有机溶剂中，得到聚酰亚胺粘合剂。因此，作为四羧酸-2-酐的二苯甲酮四羧酸-2-酐在25℃下溶解于N-甲基-2-吡咯烷酮中。 0.5摩尔的4,4'-二氨基二苯基硫醚和0.5摩尔的2,2-双（4- {3-氨基苯氧基|苯基）砜混合。将0.5摩尔的4,4-二氨基二苯基硫醚和0.5摩尔的2,2-双（4- {4-氨基苯氧基|苯基）砜搅拌5小时，得到聚酰胺酸。得到15重量％的聚酰胺酸涂布在聚酰亚胺膜上，在100℃下3分钟，130℃干燥4分钟，在200℃下干燥3分钟，在300℃下干燥1小时，得到标题胶带。
