【摘要】 含异戊二烯结构单元的嵌段共聚物,以其优异的性能,在自组装材料和纳米尺寸材料等领域得到了日益广泛的关注和研究。本文从合成的角度出发,系统地综述了聚异戊二烯嵌段共聚物的制备方法,特别介绍了基于聚异戊二烯嵌段合成的阴离子聚合以及活性自由基聚合中的氮氧自由基聚合(NMRP)、可逆加成-断裂链转移自由基聚合(RAFT)、原子转移自由基聚合(ATRP)等聚合方法。以可控聚合为基础的多种聚合技术综合运用是制备聚异戊二烯嵌段共聚物未来的发展方向。更多还原

【Abstract】 Block copolymers based on isoprene have attracted lots of attentions due to its excellent properties in the field of self-assembled materials,nanometer-sized materials and so on.In this paper,the development history of polyisoprene(PI)block copolymers was reviewed systematically in view of perspective of preparation methods involved in anionic polymerization and the living free radical polymerization including nitroxide mediate radical polymerization(NMRP),reversible addition-fragmentation chain transfer polymerization(RAFT)and atom transfer radical polymerization(ATRP).It is stated that the comprehensive application in combination of various polymerization technology based on controlled polymerization will be the future for synthesis of PI block copolymers.更多还原
