| 摘 要： | 通过淀粉纳米晶与苯乙烯乳液聚合的方法制备了聚苯乙烯接枝淀粉纳米晶并用FTIR和1HNMR进行了表征;制备了不同接枝聚苯乙烯单体与淀粉纳米晶的物质的量之比(MS)的聚苯乙烯接枝淀粉纳米晶,在苯乙烯单体和淀粉纳米晶摩尔比(M/SN)为2,反应时间为5～12h条件下,所得MS为0.15～0.67.X-射线衍射结果表明,接枝聚苯乙烯几乎不会改变淀粉纳米晶的晶型,但结晶度随着MS的增加而下降.

| Abstract: | Polystyrene-g-starch nanocrystals with different MS (mole ratio of grafted polystyrene and starch nanocrystals) were prepared by the grafting polymerization of starch crystals and styrene and characterized by FTIR and ~1H NMR. When the mole ratio of styrene monomer and starch nanocrystals (M/SN) was 2 and reaction time was between 8 and 12 h, the MS of copolymer was between 0.15 and 0.67. XRD experiments showed that the grafted polystyrene nearly had no change on the crystal type of starch nanocrystals, but... |
