Sequence control and structure regulation still remains a problem for many multi-segmentedcopolymers. However, programmable multi-component reactions based on three or more
monomers are highly worth to explore in order to solve the problem. We are longing for new
progress in polymer science and polymer engineering to solve the obstacles we are faced so far,
such as controllability and regularity in polymer syntheses, and processibility of polymers with
high degree of rigidity.
