关于甲基丙烯酸羟乙酯与甲基丙烯酸十八酯共聚出现的若干问题?最近在做聚合反应,参考一篇文献上用AIBN引发HEMA和OMA的共聚,文献上说A mixture of monomers (20 % w/v to solvent) OMA (3.6 g) and HEMA (2.4 g) and 30 mL dehydrated DMF was placed in a round bottom flask fitted with a nitrogen adaptor. Nitrogen was purged for 15 minutes to remove the oxygen and the flask was heated up to 70 C in an oil bath. AIBN (0.6 g) dissolved in DMF was added to initiate the polymerization with constant stirring. 关键是产物打了核磁,发现产物里面几乎很少有HEMA参与共聚,理论上HEMA大大过量,应该有许多参与反应的,可是实际情况很不理想,请问有没有做这一块的大佬?那里出了问题?欢迎大家留言交流。查看更多2个回答 . 12人已关注
