平衡溶胀比

采用苯中的平衡溶胀比或交联密度来表征LDPE交联物的交联程度比采用凝胶含量来表征更为确切。

It is found that equilibrium swelling ratio or crosslinking density is more appropriate parameter to characterize the difference of structure of LDPE vulcanizates by both crosslinking method .

凝胶的平衡溶胀比随着反应温度的升高逐渐增加，而KGM含量对凝胶平衡溶胀比影响不大；

The equilibrium swelling ratio of the complex gel was increased gradually with the increase of the reaction temperature , but KGM content had little effect on it .

实验表明：合成的水凝胶初始溶胀迅速，达到平衡溶胀比平衡约6h；

The results show that hydrogels swell rapidly at the beginning and the of swelling balance is 6-7 h.

探讨了有关溶胀动力学，着重考察了合成反应条件包括淀粉用量、单体浓度、引发剂和交联剂用量对凝胶平衡溶胀比的影响。

The swelling kinetics was discussed , and the effects of the reaction conditions , including the amounts of starch , monomers , initiator and crosslinker , on the equilibrium swelling ratio of the hydrogels were investigated .
