| 摘 要： | 采用复相接枝的方法，使丙烯酸丁酯分散于水中形成乳液相并与同时处于乳液相的聚羟基烷酸颗粒接枝联合；研究了引发剂的用量、丙烯酸丁酯浓度、反应时间和反应温度等对接枝反应的影响，并对接枝反应的机理进行探讨，结果表明采用亚硫酸氢钠和过硫酸钾为引发剂，十二烷在苯磺酸钠为乳化剂，丙烯酸丁酯与聚羟基烷酸的接枝率可达１５％。

| Abstract: | Polyhydroxyalkanoates were reinforced with polybutylacrylate (BA) by using the binary phase graft reaction. The effect of monomer concentration, initiator concentration, reaction time and temperature on the grafting percentage was studied and optimum conditions were obtained. The reactive mechanism was investigeted. The kinetic equation for this binary graft reaction coincides with the results of the experiment. |
