丙烯酸酯在导电炭黑表面的接枝共聚合

Graft Copolymerization of Acrylate on Conductive Carbon Black Surface

利用导电炭黑表面上引入的过氧酯基与亚铁盐构成的氧化还原体系 ,引发甲基丙烯酸甲酯和丙烯酸在炭黑表面接枝共聚合。通过透光率的分析表明 ,V(MMA) V(AA)为 7 5 12 5时 ,聚合物接枝炭黑能稳定地分散在水溶液中。

Graft copolymerization of acrylate monomers on the surface of conductive carbon black was initiated by a redox system consisting of the added iron(Ⅱ) ion and the peroxyester groups introduced onto the conductive carbon black surface. The transmittance of the dispersion system of the grafted conductive carbon black in water showed that the grafted carbon black gave a stable collidal dispersion in water when the ratio of MMA/AA was 7 5/12 5.
