摘要:
针对三元乙丙橡胶接枝顺酐接枝率测定的误差较大的现象，研究了影响接枝率测定的各种因素，如：沉淀剂及其用量、溶剂及其用量、KOH用量、回流时间、光照时间等.研究表明EPDMgMAH接枝率测定的最适宜条件为：反应混合物与沉淀剂丙酮的体积比为14；光照时间为4~8 h，以接枝物不被烤黄(焦)为宜.测定接枝率时以甲苯为溶剂与接枝物的用量比为1 g200 mL；回流时间为2~3 h；接枝物与氢氧化钾乙醇溶液用量比为1 g100 mL
Abstract:
 Since there was big errors when determining graft yield in the grafting MAH onto EPDM, all kinds of factors of determining graft yield were studied， for example, precipitant and its dosage,the kind of solvents and its dosage, the time of circumfluence and illumination,etc. The result showed that the optimum condition of determining graft yield in the grafting of MAH onto EPDM was:The precipitant as acetone and fourfold graft copolymer, the solvent when determination graft yield as toluene and the dosage as 1 g200 mL,the circumfluence time as 2~3 h, the dosage of KOHethanol as 1 g100 mL.
