WLF方程——链段运动的特殊温度依赖关系

The results showed that nanometer particles enhanced the segmental relaxation behavior of PS,and decreased the Tg of PS/nano-CaCO3 composites to same extent with the increase of nano-CaCO3 contents.

结果表明:纳米粒子加入有利于PS分子链段松弛运动,PS/纳米CaCO3复合材料的Tg随纳米粒子含量增加而有不同程度的下降。

苯乙烯/丙烯酸丁酯微乳液共聚物链段分布的研究

The influence of hydrophilic segment chain length of the polyethylene (PEG) on contact angle,water-vapor permeability,water-absorbing capacity and mechanical properties of polyurethane film was investigated.

探讨了聚乙二醇(PEG)亲水链段的分子链长,对聚氨酯薄膜表面接触角、透气性、吸水率和力学性能的影响。

The synthesis of the polyester-polyol poly-segment copolymers was studied , and a copolymer was synthesized and theoretically evaluated for its co-crystalline and hydrophilic segments and its structural characteristics by the modern analytic means such as IR, GPC and DSC.

合成了聚酯-聚醚多嵌段型共聚物,经共聚物的共晶链段和亲水链段的理论估算,合成了一种聚酯-聚醚型亲水抗静电剂。
