交联高聚物因吸收一定量溶剂而溶胀。当达到溶胀平衡时,其体积与溶胀前体积之比称为溶胀比。溶胀比与温度、压力、高聚物的交联度及溶质、溶剂的性质有关。
随着PEG臂数的增加,干胶的熔融峰顶温度下降,凝胶的溶胀比减小;
With the increase of arm numbers of PEG, the temperature of the melting peak of dried gels and the swelling ratio of hydrogels decrease;
胶平衡溶胀比随KGM 用量的增加而增加,而随STMP用量的增加而降低。
The equilibrium swelling ratio was increased with the increasing of KGM dosage and decreased with the increasing of STMP dosage.
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.
