| 摘 要： | "活性"/控制自由基聚合(CRP)可用于合成具有精确结构和窄分子量分布的聚合物.乳液聚合具有环保、经济、易控的优点,但乳液体系为多相体系,控制试剂的相间分配和迁移较均相系统复杂,这使乳液"活性"/控制自由基聚合面临一些挑战,诸如控制聚合特征差、乳液稳定性下降等.本文介绍了近年来乳液体系中的原子转移自由基聚合(ATRP)和可逆加成-断裂链转移聚合(RAFT)的研究进展,包括体系的特性、面临的挑战、解决的方法,以及工程与商业运用的前景和需要解决的问题.

| Abstract: | Controlled/living radical polymerization(CRP) provides a route to synthesize polymers with designed microstructure and narrow weight distribution. Emulsion polymerization has the advantages of environmentally benign,low cost and high controllability. However,as a heterogeneous system,phase partitioning and transport of the controlling agent between phases in emulsion are more complicated than those in homogeneous system. As a result,adaptation of CRP in emulsion system poses several challenges,such as poor ... |
