The processability and resistance to oxidative degradation of polyphenylene ether resins, alone, or in combination with a styrene resin, is improved by including a modifier comprising an alpha, beta-unsaturated carboxylic acid or derivative. In an embodiment, the formation of a composition comprising a poly(2,6-dimethyl-1,4-phenylene ether) and 2 parts per hundred of dibutyl maleate results in a 26 percent improvement in spiral flow, and a 30 percent reduction in oxygen uptake at 115°C. enhancing the utility of polyphenylene ether resins as extrusion and injection molding materials.
通过加入包含α、β-不饱和羧酸或衍生物的改性剂,可改善聚苯醚树脂单独或与苯乙烯树脂组合的加工性和抗氧化降解性。 在一个实施方案中,形成一种包含聚(2,6-二甲基-1,4-亚苯基醚)和百分之二马来酸二丁酯的组合物,可使螺旋流动性提高 26%,115°C 下的吸氧量降低 30%,从而提高了聚苯醚树脂作为挤出和注塑成型材料的实用性。
