Title (EN) MODIFIED POLYESTER COMPOSITIONS
(FR) COMPOSITIONS DE POLYESTERS MODIFIEES
Abstract: front page image
(EN)Modified thermoplastic polyester compositions which comprise (a) a poly(1,4-butylene terephthalate) resin in combination with a poly(ethylene terephthalate) resin and /or a polyester copolymer and (b) a modifier therefor comprising a combination of a selectively hydrogenated monoalkenyl arene-diene block copolymer resin and an aromatic polycarbonate. The compositions can include (c) reinforcing glass fibers and/or (d) a flame retardant. Modifier (b) provides enhanced resistance to impact fracture, increased strength and improved resistance to heat distortion in articles molded from the compositions.
(FR)Des compositions de polyesters modifiees comprennent (a) une resine de poly(1,4-terephtalate de butylene) en combinaison avec une resine de poly(terephtalate d"ethylene) et/ou un copolymere polyester et (b) un modificateur comprenant une resine d"un copolymere a bloc de monoalkenyl-arene-diene selectivement hydrogene et d"un polycarbonate aromatique. Ces resines peuvent comprendre (c) des fibres de verre de renforcement et/ou (d) un retardateur d"inflammation. Le modificateur (b) fournit une resistance accrue a la rupture par impact, une resistance mecanique accrue et une resistance amelioree a la distorsion par la chaleur des articles moules a partir de ces compositions.
