摘要

It had very long been a dream in polymer science to synthesize long multi-block polymer chains with an orderedchain sequence and controllable block lengths. Using ionic or living free radical polymerization or furnishing each end ofpolymer blocks with a reactive functional group

one can only prepare heteropolymer chains with few long blocks

such asdiblock and triblock copolymers. The most plausible result so far was a pentablock copolymer. Recently

using a combinationof polymer physics and synthetic chemistry

we have invented self-assembly assisted polycondensation (SAAP).This communication reports the results of using this novel method to connect 10-100 triblock polymer chains together to form long multi-block heteropolymer chains with an ordered sequence and controllable block lengths.
