| 摘 要： | 有关凝聚态结构对聚合物内聚能密度的影响，在高分子物理学界一直未被关注。本文首次提出了利用结晶熔融热估算晶态非极性聚合物内聚能密度的方法，并对结晶态的聚四氟乙烯、聚乙烯和聚丙烯的内聚能密度进行了估算。估算值较好地解释了上述聚合物用作塑料但内聚能密度较小的理由。结晶熔融热本质上反映了非极性聚合物的晶态与非晶态分子间色散力相...

| Abstract: | The effect of condensed structure on cohesive energy density of polymer has always been ignored in the field of polymer physics.A method for estimating the CED value of crystalline non-polar polymers based on heat of fusion was first proposed in this paper.And the CED value of Poly(tetrafluoroethylene),Polyethylene and Polypropylene in crystalline were estimated.The estimated CED value better explained those polymers for plastics but with lower CED value.Heat of fusion essentially reflects the difference of... |
