Highly elastic lactide-based polymer blends, objects made from polymer blends, and methods of manufacturing objects

摘要

(A) It has a substantially random partially block-like structure, and has a poly [(L-lactide) -co- (ε-caprolactone)] and a poly [(D-lactide) -co- (ε-caprolactone)]. )], And (B) unlike the first polymer component (A), which is a copolymer selected from poly (L-lactide), poly (D-lactide), poly [(L). -Lactide) -co- (ε-caprolactone)] and a second polymer component selected from poly [(D-lactide) -co- (ε-caprolactone)], which comprises or consist of the above. The first and second polymer components (A) and (B) are provided by polymer blends in which the resulting polymer blend is selected to include a combination of L-lactide-derived constituent units and D-lactide-derived constituent units. Will be done. Highly elastic materials can be processed by electrospinning to produce elastic porous objects with non-woven fiber structures. [Selection diagram] None
