Use of a selected combination of an ionic hydrocarbon copolymer and antimony trioxide in the presence of a halogenated flame retardant has been found to increase flame-retardancy without lowering thermal stability of a reinforced or filled polyethylene terephthalate molding blend which contains a sodium or potassium salt of an ionic hydrocarbon copolymer and a low molecular weight compound that is an ester, ketone, sulfone, sulfoxide, nitrile or amide.
研究发现,在卤化阻燃剂存在的情况下,使用离子烃共聚物和三氧化二锑的精选组合,可提高增强型或填充型聚对苯二甲酸乙二醇酯模塑混合物的阻燃性,而不会降低其热稳定性,该混合物含有离子烃共聚物的钠盐或钾盐以及酯类、酮类、砜类、亚砜类、腈类或酰胺类的低分子量化合物。
