摘要
在自由基引发剂和界面剂存在下,利用固相接枝聚合方法,反应温度为100~120℃,得到马来酸酐接枝等规聚丙烯(PP-g-MA)产物,接枝率约为2.5%(重量)。用红外光谱,宽角X射线衍射(WAXS)和^(13)CNMR固态交叉极化魔角旋转(CPMAS NMR)技术表征了产物的结构。
Isotactic polypropylene-maleic anhydride graft copolymer (PP-g-MA) (degree of grafting is 2.5%) were produced utilizing the technique of solid phase graft oopolymerization at temperature 100-120℃ and in presence of radical initiator. Copolymer structure was characterized by IR , X-ray scatter (WAXS) and CPMAS NMR.
