以甲基丙烯酸丁酯(BMA)为接枝单体，过氧化苯甲酰(BPO)为引发剂，采用固相接枝技术对聚丙烯(PP)进行改性，制备了BMA接枝PP (PP-g-BMA)。研究了接枝反应工艺条件对接枝率的影响，采用傅立叶变换红外光谱表征与分析了PP-g-BMA，并对PP-g-BMA在PP/聚对苯二甲酸乙二酯(PET)共混物中的增容作用进行了验证。结果表明，当反应温度为130℃、引发剂的质量分数为6%、单体BMA质量分数为10%，接枝反应3 h，成功制得了接枝率为3.75%的PP-g-BMA；PP-g-BMA可明显改善PP/PET共混物的界面相容性，相对于PP-g-MAH，其增容的PP/PET共混物的力学性能和加工流变性能更好。
以甲基丙烯痠丁酯(BMA)為接枝單體，過氧化苯甲酰(BPO)為引髮劑，採用固相接枝技術對聚丙烯(PP)進行改性，製備瞭BMA接枝PP (PP-g-BMA)。研究瞭接枝反應工藝條件對接枝率的影響，採用傅立葉變換紅外光譜錶徵與分析瞭PP-g-BMA，併對PP-g-BMA在PP/聚對苯二甲痠乙二酯(PET)共混物中的增容作用進行瞭驗證。結果錶明，噹反應溫度為130℃、引髮劑的質量分數為6%、單體BMA質量分數為10%，接枝反應3 h，成功製得瞭接枝率為3.75%的PP-g-BMA；PP-g-BMA可明顯改善PP/PET共混物的界麵相容性，相對于PP-g-MAH，其增容的PP/PET共混物的力學性能和加工流變性能更好。

Polypropylene grafted with butyl methacrylate (PP-g-BMA) was prepared by solid phase grafting with BMA as grafting monomer and benzoyl peroxide (BPO) as initiator. The graft product was characterized and analyzed by Fourier transform infrar-ed spectroscopy. The effects of reaction temperature,initiator dosage,monomer concentration and reaction time on the grafting ratio were studied and the compatibilization effect of PP-g-BMA on PP/polyethylene terephthalate (PET) blend was also studied. The results show that PP-g-BMA with grafting ratio of 3.75%is successfully prepared after grafting for 3 hours at 130℃when the mass fraction of the initiator and BMA is 6%and 10%separately. PP-g-BMA can evidently improve the interface compatibility of PP/PET,comparing with PP-g-MAH,the mechanical properties and processing rheological property of PP/PET/blend PP-g-BMA are better.
