REACTIVE MONOMER, AND POLYMERIZABLE COMPOSITION USING THE SAME

PROBLEM TO BE SOLVED: To provide: a reactive monomer for imparting very high coating film hardness, which has relatively low viscosity and thus excellent handleability, and causes little cure shrinkage; and a polymerizable composition which has a high cure rate accompanying the reaction and may become a basis for various applications.SOLUTION: A reactive monomer represented by the general formula (1). (R1-R3 and R5-R7 each independently represent H or an alkyl group; R4 represents a hydrogen atom, an alkyl group or a hydroxy group; and A is a divalent linking group.)SELECTED DRAWING: None 【課題】比較的低粘度でハンドリング性に優れ、なおかつ硬化収縮が少なく、非常に高い塗膜硬度を与えるための反応性モノマーの提供。更に、反応に伴う硬化速度が速く、種々の用途において基本となりうる重合組成物の提供。【解決手段】式（１）で表される反応性モノマー。一般式（１）（Ｒ１〜Ｒ３、及びＲ５〜Ｒ７は各々独立に、Ｈ、又は、アルキル基；Ｒ４は水素原子、アルキル基、又は、ヒドロキシ基を表す。Ａは２価の連結基）【選択図】なし
