摘要:
    RAFT（reversible addition fragmentation chain transfer）反应平衡常数（K）是影响乳液聚合分散稳定性以及聚合反应动力学的关键因素。为此，在相同RAFT试剂浓度下，通过苯乙烯的RAFT细乳液聚合，考察了K值分别为4.06 L/(mol·s)和314 L/(mol·s)两种RAFT试剂对聚合产物粒径分布、分子量分布以及聚合反应速率的影响。研究发现：两实验中胶乳的粒径分布相近；当采用低K值RAFT试剂时，聚合过程中未出现缓聚现象，但产物分子量分布指数（PDI）高达3.68；高K值RAFT试剂虽然引起了严重的缓聚现象，但最终产物分子量为6×104 g/mol时，其PDI仅为1.51，明显优于前者。
