摘要/Abstract

摘要： 使用再生电子转移生成催化剂原子转移自由基聚合(ARGET ATRP)方法,在微晶纤维素表面分别接枝了甲基丙烯酸甲酯(MMA)和甲基丙烯酸钠(MAA-Na),FT-IR图谱和SEM照片证明纤维素基表面成功接枝聚甲基丙烯酸甲酯(PMMA); 凝胶渗透色谱分析表明PMMA的分子质量分布较窄,M_w/M_n=1.12,说明ARGET ATRP实现了对接枝侧链分布均一性的有效控制。MAA-Na单体的转化率随反应时间的增加而增加,可在接枝侧链分布均一性的基础上通过调整反应时间实现侧链长度的有效可控。ARGET ATRP可实现对微晶纤维素表面接枝侧链分布和长度的控制。

Abstract: This paper applies ARGET(activators regenerated by electron transfer)ATRP(atom transfer radical polymerization)to graft methyl methacrylate(MMA)and sodium methacrylate(MAA-Na)from microcrystalline cellulose, respectively. The grafted substrates were evaluated with FT-IR and SEM, suggesting that polymethylmethacrylate(PMMA)was successfully grafted from the surface of microcrystalline cellulose. The free polymer PMMA was characterized by GPC, showing that the molecular weight distribution was narrow(M_w/M_n=1.12)and sufficient control was achieved when grafting monomers from the cellulose substrates via ARGET ATRP. Furthermore, the influence of time on grafting microcrystalline cellulose with MAA-Na through ARGET ATRP was investigated. The results revealed that monomer conversion increased with the reaction time, corroborating that ARGET ATRP can get good control on the length of the side chains grafted from the substrates. The distribution and the length of polymer chains graftod from microcrgstalline celluloso can be well controlled by ARGET ATRP.
