比较Charlesby-Pinner及陈欣方-刘克静-唐敖庆(简称陈-刘-唐)关系式在高分子辐射交联反应中的适用情况,研究了高分子链结构对辐射交联反应的影响。具有较高的Tg(玻璃化转变温度)及σ(内旋转让阻因子)值的刚性链高分子和结构单元中含有辐射裂解型单体的高分子,符合Charlesby-Pinner关系式。支化高分子和具有较低的Tg及σ值的柔性链高分子符合陈-刘-唐关系式。
The application of the relationship between Charlesby-Pinner and Chen Xinfang-Liu Kejing-Tang Aoqing (Chen-Liu-Tang) in polymer radiation crosslinking reaction was studied. The effect of polymer chain structure on radiation crosslinking reaction was studied. Rigid chain macromolecules with higher Tg (glass transition temperature) and σ (internal rotation transfer resistance) values and polymers containing a radiation-cleaving monomer in the structure units are in accordance with the Charlesby-Pinner relationship. Branched macromolecules and flexible chain macromolecules with lower Tg and σ values fit the Chen-Liu-Tang relation.
