这个8小时的实验(分两个4小时的课程)旨在让学生掌握聚合物合成的基本技能，特别是合成分子量明确的聚合物。本实验通过活性自由基聚合法，特别是可逆加成断裂链转移(RAFT)过程，合成和表征了聚(新十一酸乙烯酯)。所使用的RAFT试剂(乙基黄原酸)的商业可获得性使得无需求助于广泛的合成化学即可进行有效的实验室实践。通过目前的实验，本科生在活的自由基聚合技术中获得了宝贵的实验室经验，这种聚合技术已经彻底改变了当代的聚合物科学。
This 8-hour experiment (spread over two 4-hour sessions) is designed to equip students with essential skills in polymer synthesis, particularly in synthesizing polymers of well-defined molecular weight. The experiment involves the synthesis and characterization of poly(vinyl neodecanoate) via living free radical polymerization, specifically the reversible addition fragmentation chain transfer (RAFT) process. The commercial availability of the RAFT agent employed (ethylxanthogenacetic acid) enables an efficient laboratory practice without recourse to extensive synthetic chemistry. Through the current experiment, undergraduate students gain invaluable laboratory experience in one of the living free radical polymerization techniques that has revolutionized contemporary polymer science
