【摘要】 研究了利用酸碱中和滴定法测定马来酸酐接枝聚丙烯中酸酐含量的测试方法,分析了取样量、KOH-乙醇标准溶液浓度、滴定温度等因素对测试结果的影响,进而得到优化的试验方法。该方法具有操作简单、投资少等优点,适合于接枝物产量小的中小型企业使用。更多还原

【Abstract】 The method of determining acid anhydride content in maleic anhydride graft polypropylene by nentralization titration was studied. The effects of factors such as the quatity of the refined sample, the concentration of KOH-ethanol standard solution, the titration temperature was analysed, and a optimized experimental method was achieved. The method had advantages such as operating simply, small investment for equipment, and it was suitable for minitype corporation which had a small out of grafted materials.更多还原
