PBA/PMMA制备过程及结构控制基础研究

Fundamental study on Preparation Process and Structure Coutrol of PBA/PMMA

研究甲基丙烯酸甲酯(MMA)在交联聚丙烯酸丁酯(PBA)中的扩散,发现交联PBA吸附MMA达饱和状态的时间随PBA交联密度和温度的增加而缩短。80℃下,饱和状态的时间仅为12-20 min。

The adsorption of MMA into crosslinked PBA was studied , It was found that the saturated adsorption time （teq） of MMA into the crosslinked PBA increases with the decrease of its crosslinking density and temperature （T）. teq-T relationship has been established as follows： teq = 322.7- 238.7 1/T＋45.56（1/T）^2.The saturated adsorption time for PBA particles at 80℃ has been measured to be about 12-20 min.
