PURPOSE:To prepare the title compsn. excellent in wet heat resistance, flame retardance, and flowability by compounding a polybutylene naphthalenedicarboxylate with a brominated epoxy flame retardant and, if necessary, a specific auxiliary flame retardant and an inorg. filler. CONSTITUTION:30-99.5wt.% polybutylene naphthalenedicarboxylate, 0.5-25wt.% brominated epoxy flame retardant of the formula (wherein (n) is 0-50), 0-15wt.% at least one auxiliary flame retardant selected from the group consisting of Sb2O3 and xNa2O.Sb2O5.yH2O (wherein (x) is 0-1; and (y) is 0-4), and 0-50wt.% inorg. filler (pref. glass or carbon fibers) are compounded to give the title compsn., which is excellent in wet heat resistance, flame retardance, and flowability. |
