Analysis of Controllable Gradient Copolymers Synthesized by Chemical Semi-continuous Reactor and RAFT Technology
This article uses semi continuous feeding method and RAFT technology to synthesize controllable gradient copolymers.Through experimental design,a series of St/BA copolymers with precise controllable composition curves are synthesized,and the RAFT reagent selected is BDIB.The feed rate of the comonomer was calculated through a kinetic model based on the composition chain length curve of the target copolymer.The composition distribution,molecular weight,and molecular weight distribution of the obtained copolymer were consistent with the model predictions.
