METHOD FOR PRODUCING BORON NITRIDE FIBER FROM BORYL BORAZINE

摘要

PROBLEM TO BE SOLVED: To provide a precursor polymer for fibers which solves the defects of the conventional technique, and particularly has desired quality relating to the production of born nitride fibers.;SOLUTION: The polymer is represented by formula (1) (wherein n is an integer; R¹ and R² are the same or different and each independently an alkyl group; and R³ is an amino group, a hydrogen atom, an alkyl, a cycloalkyl or boryl).;COPYRIGHT: (C)2003,JPO
