  • Patent number: 11643548
    Abstract: 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-(£-caprolactone)] and poly[(D-lactide)-co-(£-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-(£-caprolactone)] and poly[(D-lactide)-co-(£-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 produce elastic porous objects having a non-woven fibrous structure.
    Type: Grant
    Filed: September 26, 2018
    Date of Patent: May 9, 2023
    Assignee: HELMHOLTZ-ZENTRUM HEREON GMBH
    Inventors: Andreas Lendlein, Axel Thomas Neffe, Paul Jakob Hommes-Schattmann, Quanchao Zhang
  • Patent number: 11618980
    Abstract: The invention provides a surface-functionalised polymeric object (10), comprising: a bulk material (11) comprising a copolymer containing constitution units derived from a first comonomer and constitution units derived from a second comonomer, the first comonomer being selected from L-lactide and D-lactide and forming sequences of oligo(L-lactide) or oligo(D-lactide) in the copolymer the copolymer having a substantially random, partially blocky structure with a dyad ratio of (lactide-lactide)-dyads to (lactide-second comonomer)-dyads of at least 2.
