A two-step process for lactic acid polymerization is studied: in the first step the lactic acid is condensation-polymerized to a low-molecular-weight hydroxylterminated prepolymer; and then the molecular weight is raised by joining prepolymer chains together using diisocyanate as the chain extender.
## Abstract Macromonomers are valuable synthetic building blocks: They can be copolymerized with low molecular weight monomers to generate brush‐like structures or serve as conjugation substrates in pericylic, metathesis, and thiolene reactions. Based on earlier reports on the facile high temperatu
