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。
