摘要:
聚丙烯(PP)作为通用塑料存在常规产品过剩与功能化产品严重短缺的问题，对PP进行接枝改性是实现其高性能化的重要方法。利用微波诱导固相接枝的方法，将极性单体马来酸酐(MAH)接枝在PP表面，通过添加第二单体苯乙烯(St)来提高接枝率，并对制备的马来酸酐接枝聚丙烯(PP g MAH)进行特性表征。结果表明：红外谱图显示PP成功接枝了MAH和St，添加St后最大接枝率可高达1.4%；改性后的接枝产物熔点几乎不变，而结晶温度有所提高，达到110.8 ℃；熔体流动速率均低于30 g/10min，较PP（38.7105 g/10min）下降明显，复数黏度更是从53.828 Pa·s提升至419.46 Pa·s；PP与水接触角从125.4°最多降至100°，PP g MAH的极性提高，亲水性能改善。该研究利用微波诱导PP固相接枝MAH，方法简单高效，在获得高接枝率的同时避免了分子量下降，改善了材料的性能，具有较为广阔的应用前景。
