摘　　要：将科研成果“2-乙烯基吡啶的常温RAFT聚合”设计成高分子化学综合性实验。以2-乙烯基吡啶为聚合单体,以S-十二烷基-S’-(α,α”-甲基-α”-乙酸)三硫代碳酸酯(DDMAT)为链转移剂,不添加还原性引发剂,仅加入氧化性中温引发剂过氧化苯甲酰(BPO),进行RAFT聚合。结果表明,设计的2-乙烯基吡啶的RAFT聚合实验,可在常温下进行,操作简便,制得的聚2-乙烯基吡啶结构可控,分子量分布窄(PDI<1.20)。从促进学生掌握聚合物合成的基本实验操作技术和大型仪器的操作技能,拓展学生的学术视野,提高学生的实践和创新能力。The scientific research achievement of“RAFT polymerization of 2-vinylpyridine at ambient temperature”is designed for the comprehensive experiment of polymer chemistry.The RAFT of 2-vinylpyridine with S-1-dodecyl-S-(α,α-dimethyl-α-aceticacid)trithiocarbonate(DDMAT)as chain transfer agent without a reductive initiator has been proceeded with in the presence of an oxidation mesothermal initiator only,i.e.,benzoyl peroxide.The results showed that RAFT polymerization of 2-vinylpyridine could be carried out easily at room temperature;the structure of the prepared Poly(2-vinylpyridine)could be controlled with narrow molecular weight distribution(PDI<1.20).The experiment can help students to master basic experimental techniques of synthetic polymer,master skills of operating large instrument,broaden students’academic horizons,and improve their practical and innovative abilities.
