(METH)ACRYLIC MONOMER AND METHOD FOR PRODUCING SAME

The present invention is a (meth)acrylic monomer represented by general formula (1) (wherein R1 represents a hydrogen atom or a methyl group; R2 to R4 independently represent -CH3 or -CH2-O-R5, wherein at least one of R2 to R4 represents -CH2-O-R5; R5 represents an alkyl group having 1 to 4 carbon atoms; and Z represents multiple atoms necessary for the formation of an alicyclic hydrocarbon grouphaving 3 to 10 carbon atoms in conjunction with a carbon atom). The (meth)acrylic monomer has a high property of being removed by the action of an acid (i.e., high acid degradability). 本发明涉及一种下述通式(1)所示的(甲基)丙烯酸单体，式中，R为氢或甲基，R～R独立地为-CH或-CH-O-R，且R～R中的至少一个为-CH-O-R，R为碳原子数1～4的烷基，Z表示与碳原子共同形成碳原子数3～10个的脂环烃基所需的多个原子。该(甲基)丙烯酸单体具有基于酸的高脱离性(高酸分解性)。
