中文摘要：
研究了聚丙烯（PP）固相接枝马来酸酐（MAH）的反应温度,MAH和引发剂（BPO）用量等对产物接枝率和熔体质量流动速率等的影响。结果表明：120℃左右是制备高接枝率产物的最适宜反应温度;MAH和BPO用量分别为10%和5%左右时接枝产物的接枝率相对较高,同时其熔体质量流动速率和接枝效率也较为适当和合理;溶胀PP固相粒子的二甲苯用量也应适当控制,过量会造成操作及对接枝率不利等问题;接枝产物的熔点比PP纯样的低,而MAH的引入有利于结晶成核。
英文摘要：
The effects of the temperature,content of maleic anhydride（MAH）and benzoyl peroxide（BPO）on the grafting ratio and melting flow rate of grafting product were studied.The results indicated that the optimum reaction temperature to prepare grafting product with high grafting ratio was 120 ℃;when the contents of initiator and MAH monomer were 5% and 10% respectively,the grafting ratio of polypropylene（PP）grafting product was relatively higher,at the same time,its melting flow rate and grafting efficiency were opportune;the content of dimethylbenzene used for swelling of the solid PP should be properly controlled,but its overdose would lead to some problems,such as operation and grafting ratio;the melting point of grafting products was lower than neat PP,while the addition of MAH was beneficial to crystallization nucleation of grafting products.
