Description
本發明涉及適於接著劑之胺甲酸酯(甲基)丙烯酸酯及其製造方法、包含前述胺甲酸酯(甲基)丙烯酸酯之硬化性組成物以及其硬化物。
胺甲酸酯(甲基)丙烯酸酯藉由作為單體使用,可獲得柔軟性或韌性、耐衝擊性、接著性等各種特性優異之機能性高分子,由此來看胺甲酸酯(甲基)丙烯酸酯係一作為單體來說廣用性高的化合物。舉其用途之一例,係可作為影像顯示裝置之觸控面板周邊等要求耐衝擊性之處的接著劑成分來利用。
胺甲酸酯(甲基)丙烯酸酯之合成方法一般為下述方法:使異氰酸酯基末端預聚物與具有羥基及(甲基)丙烯醯氧基之化合物(例如丙烯酸2-羥乙酯等)進行反應。又,亦已知有一合成方法係使多元醇與具有異氰酸酯基及(甲基)丙烯醯氧基之化合物進行反應。
以該等合成方法而得之胺甲酸酯(甲基)丙烯酸酯,其原料之多元醇的種類會大幅影響將該胺甲酸酯(甲基)丙烯酸酯作為單體使用而得之硬化物的特性差異。
例如,專利文獻1中記載了一種(甲基)丙烯醯基改質聚醚(胺甲酸酯(甲基)丙烯酸酯),其係使用數量平均分子量為3000~15000之聚醚多元醇作為多元醇,且使該聚醚多元醇與2-(甲基)丙烯醯氧基乙基異氰酸酯進行反應而得者。
