中文摘要：

范德华作用是存在于小分子间和聚合物的重复单元间的作用能．单个分子由于范德华相互作用凝聚成相．

英文摘要：

The condensed behavior of polymer fluids were studied based on the van der Waals interaction. By comparing the phase diagram of pure polymer fluids and that of van der Waals non-ideal fluids, it is found that （ 1 ） pure polymer fluids show a similar phase diagram to van der Waals non-ideal fluids ; （ 2 ） the differences between the phase diagrams were caused by the difference of chain lengths. It is explained that why the vapor pressure of polymer is hard to detect and why the negative pressure can exist in polymer liquids. It is also found that some scaling relations exist between the reduced critical pressure and the chain length, and the reduced critical volume and the chain length.
