| 摘要 |
The invention relates to a flame-retardant polyester composition comprising a poylester derived from alkylene glycol that consists largely of ethylene glycol, 2-50 wt.%, relative to the polyester, of a complex oxalate and 5-100 wt.%, relative to the oxalate, of a synergist chosen from the group comprising oxides of metals of groups 8-10 and group 15, compounds derived therefrom, borates and silicates. Preferably use is made of antimony trioxide. The invention is particularly suitable for glass-fibre-reinforced polyester compositions which then meet the UL-94 V-0 qualification. |
