ABSTRACT:
The present invention relates to an oxetane compound containing a (meth)acryloyl group represented by formula (1) having a high copolymerizability with compounds containing a (meth)acryloyl group, and to a production method of an oxetane compound containing a (meth)acryloyl group which is characterized by reacting an isocyanate compound having a (meth)acryloyl group represented by formula (5) with an oxetane compound containing a hydroxyl group represented by formula (6).(In the formula, R1represents a hydrogen atom or a methyl group, A represents —OR2— or a bond, R2represents a divalent hydrocarbon group which may contain an oxygen atom in the main chain, R3represents a linear or branched alkylene group having 1 to 6 carbon atoms, and R4represents a linear or branched alkyl group having 1 to 6 carbon atoms.)
