聚氧丙烯聚氧乙烯共聚物 P123和F127
P123和F127都是三嵌段聚合物他們都是聚醚的一種 EO-PO型聚醚Pluronic F127 而P123 全稱為:聚氧乙烯-聚氧丙烯-聚氧乙烯 其分子式為:PEO-PPO-PEO 35℃時(shí)F127和P123在ccm后可生成內(nèi)核PO分分別為92.7%和94.5%的膠束,后者膠束內(nèi)核體積為前者的2.8倍,稠環(huán)芳烴和空膠束的第一步締合平衡常數(shù)K1值均隨蔡、蒽、芘順序逐漸增大。蔡、蒽、芘在每個(gè)F127和P123膠束中的增溶量均隨膠束內(nèi)核體積增大而線性增加,每個(gè)PO基團(tuán)對應(yīng)的增溶量比十二烷基磺酸膠束內(nèi)核中相同體積應(yīng)的增溶量約大近2倍,Pluronic膠束除與稠環(huán)芳烴間具有強(qiáng)相互作用力外,所形成的大力核是導(dǎo)致大增溶量的重要因素。
