Molded articles having a maximum thickness of 3 centimeters and including a polyetherimide composition are described. The polyetherimide compositions include 60 to 99.9 weight percent of a polyetherimide having a weight average molecular weight of 5,000 to 80,000 Daltons, and 0.1 to 40 weight percent of an aryl phosphate having a molecular weight from 500 to 1,200 Daltons, wherein weight percent is based on the total weight of the composition. The compositions have a melt flow at least 10% greater than the melt flow of the same polyetherimide composition without the aryl phosphate, measured according to ASTM D1238 at 337° C. under a 6.7 kilogram load.
描述了最大厚度为 3 厘米的模塑制品,其中包括一种聚醚酰亚胺组合物。聚醚酰亚胺组合物包括 60 至 99.9 重量百分比的聚醚酰亚胺,其重量平均分子量为 5,000 至 80,000 道尔顿,以及 0.1 至 40 重量百分比的芳基磷酸酯,其分子量为 500 至 1,200 道尔顿,其中重量百分比基于组合物的总重量。根据 ASTM D1238 标准,在 337 摄氏度、6.7 千克负荷下测量,该组合物的熔体流动性比不含芳基磷酸酯的相同聚醚酰亚胺组合物的熔体流动性至少高 10%。
