Flame-resistant glass-fiber reinforced polytetramethylene terephthalate resin composition

Abstract

Abstract A flame-resistant glass-fiber reinforced resin composition comprising glass-fiber filled polytetramethylene terephthalate, a flame retardant, and antimony trioxide, characterized in that said flame retardant consists of a compound represented by the general formula (I), wherein X represents a chlorine or bromine atom and R represents a residue for connecting the left and right ring structures to form a tetrahydrofuran, cyclopentane, cyclooctane, endomethylenecylohexane, or endomethylenehydroindan ring and a halogenated bisphenol-based epoxy resin having a degree of halogenation of 10% by weight or more and represented by the general formula (II), WHEREIN Y represents a chlorine or bromine atom, each of i, j, k, and l represents a number of from 1 to 4, and (n + m) represents a mean degree of polymerization in the range of from 0 to 10; the proportions of the compounds of the formulas (I) and (II) being 3 to 30 parts by weight and 0.3 to 25 parts by weight, respectively, per 100 parts by weight of said polytetramethylene terephthalate and the weight ratio of said flame retardant to said antimony trioxide being 0.25 - 6.00 to 1. The present composition is excellent in mechanical properties, thermal properties, moldability and flame resistance.
