多面体齐聚倍半硅氧烷 polyhedral oligomeric silsesquioxanes
研究了聚酯熔体在螺杆输送、管道输送过程中及静态高温状态下齐聚物含量的变化。
The change of oligomer content was analyzed at static high-pressure state during polyester melt transfer course in screw extruder and pipes.
在一定的螺杆转速下，温度越高，停留时间越长，聚酯熔体输送过程中齐聚物含量越高。
The higher the temperature and the longer the resident time was, the higher the oligomer content was during polyester melt trans - fer course at a fixed screw rotation speed.
采用两步法工艺路线，以PA6齐聚物、聚醚和少量交联剂为原料共聚合成聚醚酰胺热塑性弹性体(TPAE)。
Polyether amide thermoplastic elastomer (TPAE) was synthesized via two-step process by using PA6 oligomer and PEG as primary material and a fixed amount of crosslinking agent.
