POLYFUNCTIONAL OXETANE COMPOUND, METHOD FOR PRODUCING THE SAME AND CATION CURABLE COMPOSITION COMPRISING THE OXETANE COMPOUND

摘要

PROBLEM TO BE SOLVED: To obtain a polyfunctional oxetane compound having low volatility in a liquid state, providing a cured material having excellent heat resistance. SOLUTION: This polyfunctional oxetane compound is represented by formula (1) (X is an oxetane alcohol unit of formula (2) (R is a methyl group or an ethyl group); Y is a methoxy group or an ethoxy group; l is an integer of 0-2, m is an integer of 0-3 and n is an integer of 0-10; a case in which m is 3 and n is 0 is omitted).
