Abstract
Oxetane compounds represented by general formula (1), which are excellent in radical polymerizability and cationic polymerizability and in compatibility and copolymerizability with other copolymerizable monomers; a process for producing the compounds; and an oxetane copolymer which is excellent in compatibility among the monomer units and has a low water absorption and excellent transparency. [In general formula (1), substituent R1 is hydrogen, alkyl, fluorine, fluoroalkyl, allyl, aryl, furyl, or thienyl; substituents R2, R3, and R4 each independently is hydrogen or C1-6 alkyl; and m and n each is an integer of 1 to 10 (provided that not all of R2, R3, and R4 are hydrogen)].
