Description
(実施例1)
撹拌装置、冷却管、滴下ロット及び窒素導入管を備えた反応器に、グリシジルメタクリレート(GMA)110g、メチルメタクリレート(MMA)30g、スチレン60g、ブチルアセテート(BA)1500g及び2,2'―アゾビスイソブチロニトリル(AIBN)2.5gを投入した。
ポリカーボネートジオールを除いては、実施例1と同一の方法でハードコーティング形成用シートを製造した。
ポリカーボネートジオールの代わりにアクリレートポリオールを用いたことを除いては、実施例1と同一の方法でハードコーティング形成用シートを製造した。
(1)低温成形性評価
実施例1及び比較例1,2で製造されたハードコーティング形成用シートに、デコレーション効果付与のための印刷層及び接着剤層をコーティングした後、十分にエージングをした。その後、シートを−10℃の温度で、1時間、低温チャンバで保管し、取り出して直ぐ射出した後、UV硬化器に通過させてから成形性を評価した。
実施例1及び比較例1ないし2で製造されたハードコーティング形成用シートに、デコレーション効果付与のための印刷層及び接着剤層をコーティングした後、十分にエージングをした。その後、シートを射出した後、UV硬化器に通過させてからスリップ性を評価した。
表1は、実施例1及び比較例1ないし2によって製造されたハードコーティング形成用シートの物性評価結果を示したものである。
