CRYSTALLINE AROMATIC POLYKETONE COPOLYMER AND MANUFACTURING THE SAME

摘要

A copolymer which can be employed for various molded particles, particularly for uses which require a high nonflammability which copolymer is a crystalline aromatic polyketone type copolymer which has an 0.40 and has a linear polymer structure comprising structural units (A) represented by the formula (A) structural units (B) represented by the formula (B) , and structural units (C) represented by the formula (C1) or by the formula (C2) the molar ratio of said units (B) to said units (C) being in the range from 30 : 70 to 99 : 1, and the unit (A) and either the unit (B) or the unit (C) being linked alternately; and a process producing the same.
