Title (EN) MULTIPLE PHASE POLYMERIC COMPOSITIONS
(FR) COMPOSITIONS POLYMERES DE PHASE MULTIPLE
Abstract:
(EN) An article, suitable for use as a body implant, is made from a novel composition comprising a multiple phase polymer composition comprising: a) a first phase which comprises a substantially non-hydrophilic polymeric component; and b) a second phase which comprises a hydrophilic polymeric component; said composition (i) being capable of absorbing water to an extent that it softens with a softening ratio of at least about 2:1 and/or swells with a swelling ratio of at least about 1.3:1, and (ii) when substantially completely hydrated has an energy to break of at least about 700 N-cm/cm3 and a 2.5% Secant modulus of less than about 7,000 N/cm2.
(FR) Un article pouvant être utilisé comme implant corporel est fait d'une composition polymère de phase multiple comprenant: a) une première phase d'un composant polymère sensiblement non-hydrophile; et b) une deuxième phase d'un composant polymère hydrophile. Ladite composition (i) est capable d'absorber de l'eau à un point tel qu'elle se ramollit dans une proportion de ramollissement d'au moins 2:1 environ et/ou se gonfle dans une proportion de gonflement d'au moins 1,3:1 environ; et (ii) lorsque complètement hydratée a une résistance à la rupture égale à au moins 700N-cm/cm3 et un module de sécante à 2,5% de moins de 7.000N/cm2 environ.
