    Abstract: Blends comprising 65-95 wt % poly(trimethylene terephthalate-co-sebacate), 5 to 35 wt % polylactic acid and a chain extender are provided that exhibit greatly increased melt strength compared to that of poly(trimethylene terephthalate-co-sebacate) alone. Such improvements allow these compositions to be processed readily by melt-blowing, which is useful for packaging and for preparing items such as biodegradable garbage bags.

    Abstract translation: 提供包含65-95重量%聚(对苯二甲酸丙二醇酯 - 共 - 癸二酸酯),5-35重量%聚乳酸和扩链剂的共混物,其显示出与单独的聚对苯二甲酸丙二醇酯 - 共 - 癸二酸酯相比显着增加的熔体强度 。 这些改进使得这些组合物可以通过熔喷容易地加工,这对于包装和制备诸如可生物降解的垃圾袋的物品是有用的。
