HIGHLY ELASTIC LACTIDE-BASED POLYMER BLEND, OBJECT MADE FROM THE POLYMER BLEND AND METHOD OF PRODUCING THE OBJECT

A polymer blend is provided, comprising or consisting of: (A) a first polymer component, being a copolymer having a substantially random, partially blocky structure and selected from poly[(L-lactide)-co-(epsilon-caprolactone)] and poly[(D-lactide)-co-(epsilon-caprolactone)] and (B) a second polymer component different from the first polymer component (A) selected from poly(L-lactide), poly(D-lactide), poly[(L-lactide)-co-(epsilon-caprolactone)] and poly[(D-lactide)-co-(epsilon-caprolactone)], wherein the first and second polymer components (A) and (B) are selected such that the resulting polymer blend comprises a combination of constitution units derived from L-lactide and constitution units derived from D-lactide. The highly elastic material may be processed by electrospinning to produceelastic porous objects having a non-woven fibrous structure. 本发明提供了一种聚合物共混物，所述聚合物共混物包含以下物质或由以下物质组成：(A)第一聚合物组分，所述第一聚合物组分是具有基本上无规的部分嵌段结构的共聚物，并且选自聚[(L-丙交酯)-共聚-(ε-己内酯)]和聚[(D-丙交酯)-共聚-(ε-己内酯)]，以及(B)不同于所述第一聚合物组分(A)的第二聚合物组分，所述第二聚合物组分
