Poly(l-lactide) and Poly(l-lactide-co-trimethylene carbonate) Melt-Spun Fibers: Structure–Processing–Properties Relationship

l-Lactide/trimethylene carbonate copolymers have been produced as multifilament fibers by high-speed melt-spinning. The relationship existing between the composition, processing parameters and physical properties of the fibers has been disclosed by analyzing how the industrial process induced changes at the macromolecular level, i.e., the chain microstructure and crystallinity development. A poly(l-lactide) and three copolymers having...
