摘要
采用溶液聚合方法,以极性马来酸酐(MAH)为桥接剂,利用其上的酸酐基团和聚乙二醇(PEG)的端羟基进行酯化反应制备聚乙二醇接枝聚丙烯。用正交实验考察马来酸酐用量,加料次数,过氧化苯甲酰(BPO)用量及反应温度等参数对产物接枝率的影响,找出影响因素的显著性,最后利用得到的产品制备聚乙二醇接枝聚丙烯。利用红外光谱(IR)、热重分析(TG)、及差示扫描量热分析(DSC)对PP-g-MAH、PP-g-PEG的结构进行表征。
In this paper,polypropylene grafted polyethylene glycol（PP-g-PEG） copolymer were synthesized in the solution polymerization using maleic anhydride as coupling.The operation conditions of grafting MAH onto PP were optimized by orthogonal experiment.The variance analysis influences of the amounts of grafting MAH onto PP,Maleic anhydride consumption,feeding frequency,initiator BPO amount,reaction temperature were investigated and found the impact on factors that high grafting yield products.The structure and performance of MPP and PP-g-PEG were confirmed by Infrared Spectroscopy,TGA and DSC.
