Description
本發明涉及適於塗覆劑之胺甲酸酯(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,係作為表面保護用塗覆劑成分來利用,其可用以防止影像顯示裝置之顯示器或觸控面板等之傷痕或破裂等。
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,該異氰酸酯基末端預聚物係使多元醇與多異氰酸酯以令多元醇之羥基相對於多異氰酸酯之異氰酸酯基的莫耳比率大於1之方式進行反應而成者。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中記載了一種胺甲酸酯(甲基)丙烯酸酯,其係使異氰酸酯基末端預聚物與丙烯酸2-羥乙酯進行反應而得者,該異氰酸酯基末端預聚物係使用具有3個羥基且以羥值換算之分子量為4000~7000的聚丙二醇合成而成者。

將本說明書中之用語及表記的定義及意義顯示於下。
「(甲基)丙烯醯氧基」係丙烯醯氧基及甲基丙烯醯氧基之總稱。同樣地,「(甲基)丙烯酸」係丙烯酸及甲基丙烯酸之總稱,而「(甲基)丙烯酸酯」係丙烯酸酯及甲基丙烯酸酯之總稱。

[胺甲酸酯(甲基)丙烯酸酯]
本發明胺甲酸酯(甲基)丙烯酸酯係以下述式(1)表示,且Mn為7500~60000。
R

n…(1)
式(1)中,R
1係從1分子中具有n個羥基之多元醇去除羥基後之n價殘基,且n為3以上,該多元醇係選自聚醚多元醇、聚酯多元醇及聚碳酸酯多元醇。1分子中之n個R
2分別獨立為從單異氰酸酯去除異氰酸酯基後之殘基,該單異氰酸酯係1分子中具有1個以上(甲基)丙烯醯氧基者。
吾等認為所述胺甲酸酯(甲基)丙烯酸酯具有源自較以往更高分子量之多元醇的骨架,且分子量分布狹窄,因此將其作為單體而得之硬化物容易形成均一之交聯網絡。因此,即便為高分子量,黏度仍較低而處置性優異,從而可獲得拉伸強度大、儲存剪切彈性模數大、殘留應變小、韌性及彎折時之形狀回復性優異且形狀保持性優異之硬化物。
本發明胺甲酸酯(甲基)丙烯酸酯係以前述式(1)表示之化合物。
由迅速聚合的觀點來看,胺甲酸酯(甲基)丙烯酸酯宜為胺甲酸酯丙烯酸酯。
(R
1)
式(1)中,R
1係從1分子中具有n個羥基之多元醇去除羥基後之n價殘基,且n為3以上,該多元醇係選自聚醚多元醇、聚酯多元醇及聚碳酸酯多元醇。
多元醇由複數種構成時,n係從各多元醇之含有比率算出之1分子中之平均羥基數。
多元醇於1分子中具有3個以上羥基,宜具有4~10個,較宜具有4~8個。具有源自所述羥基數之多元醇之骨架的胺甲酸酯(甲基)丙烯酸酯所形成的硬化物,會以高密度形成交聯網絡,而容易獲得良好之形狀保持性。
又,藉由羥基數為4個以上,容易獲得儲存剪切彈性模數高、拉伸強度及表面硬度高的胺甲酸酯(甲基)丙烯酸酯所形成的硬化物,且所述硬化物之表面不易致傷。且,具有源自羥基數為10個以下之多元醇之骨架的胺甲酸酯(甲基)丙烯酸酯所形成的硬化物,其形狀穩定性會變更良好。
從藉由該胺甲酸酯(甲基)丙烯酸酯而得之硬化物在彎折時之形狀回復性更優異的觀點來看,多元醇宜為聚醚多元醇。
<聚醚多元醇>
聚醚多元醇宜為具有3個以上羥基且具有氧伸烷基作為結構單元之聚合物。聚醚多元醇可使具有環狀醚結構之化合物對具有3個以上活性氫之引發劑開環聚合而得。又,亦可使用市售物。聚醚多元醇可為單獨1種,亦可為2種以上。
