Abstract:The synthesis of high-/ultrahigh-molecular-weight poly(L-lactide) (PLLA) having a controlled morphology remains a challenge because of the low crystallization rate of the material and the absence of a proper nucleation site during polymer synthesis. Using three different polymerization routes, the synthesis of highand ultrahigh-molecular-weight PLLA (weight-average molecular weight up to 1.1 million g/mol) having a well-defined particle morphology is reported. A comparative study on the evolution of the struct… Show more
