Minimizing the time gap between service lifetime and complete resorption of degradable melt-spun multifilament fibers

We have succeeded to modulated the degradation rate of poly(l-lactide) (PLLA) melt-spun multifilament fibers to extend the service lifetime and increase the resorption rate by using random copolymers of l-lactide and trimethylene carbonate (TMC). The presence of TMC units enabled an overall longer service lifetime but faster degradation kinetics than PLLA. By increasing the amount of TMC up to 18 mol%, multifilament fibers characterized by a...
