Title (EN) HIGHLY ELASTIC LACTIDE-BASED POLYMER BLEND, OBJECT MADE FROM THE POLYMER BLEND AND METHOD OF PRODUCING THE OBJECT
(FR) MÉLANGE HAUTEMENT ÉLASTIQUE DE POLYMÈRES À BASE DE LACTIDE, OBJET FABRIQUÉ À PARTIR DU MÉLANGE DE POLYMÈRES ET PROCÉDÉ DE PRODUCTION DE L'OBJET
Abstract:
(EN) 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.
(FR) L'invention concerne un mélange de polymères, pourvu ou constitué : (A) d'un premier constituant polymère, qui est un copolymère présentant une structure sensiblement aléatoire, partiellement séquencée, et qui est choisi parmi le poly[(L-lactide)-co-(£--caprolactone)] et le poly[(D-lactide)-co-(£--caprolactone)] et (B) d'un second constituant polymère différent du premier constituant polymère (A) choisi parmi le poly(L-lactide), le poly(D- lactide), le poly[(L-lactide)-co-(£--caprolactone)] et le poly[(D-lactide)-co-(£--caprolactone)], les premier et second constituants polymères (A) et (B) étant choisis de sorte que le mélange de polymères obtenu comprenne une combinaison de motifs de constitution dérivés de L-lactide et de motifs de constitution dérivés de D-lactide. Le matériau hautement élastique peut être traité par électrofilature afin de produire des objets poreux élastiques ayant une structure fibreuse non tissée.
