<P>PROBLEM TO BE SOLVED: To provide a cyclic phosphazene compound that increases flame retardancy and dielectric characteristics of a resin molded body without decreasing high-temperature reliability and mechanical characteristics. <P>SOLUTION: An oligo(phenyleneoxy) group-containing cyclic phosphazene compound modified with a cyanate group is provided, which is expressed by formula (1). In formula (1), n represents an integer of 1 to 6; in a plurality of A, at least one A represents a phenyleneoxy group expressed by formula (3) and others represent an aryloxy group. In formula (3), q represents an integer of 1 to 50; and E<SP POS="POST">6</SP>to E<SP POS="POST">9</SP>represent a hydrogen atom, an alkyl group or the like. <P>COPYRIGHT: (C)2013,JPO&INPIT |
