Patent

CA 2481765

A gel material and medical articles including such material, wherein the transparent gel material includes a polymerized poly(alkylene oxide) macromonomer that, prior to polymerization is a free-radically polymerizable, multifunctional (preferably difunctional), having a weight average molecular weight of at least 2000, wherein the multifunctional poly(alkylene oxide) macromonomer comprises a copolymeric random alkylene oxide moiety of the formula: -(-CH(R1)-CH2-O-)m...(-CH2-CH2-O-)n- wherein the mole ratio of m:n is within a range of about 1:9 to about 9:1.

L'invention concerne un gel et des articles médicaux comprenant un tel gel. Ce gel transparent comprend un macromonomère poly(oxyde d'alkylène) polymérisé qui, avant polymérisation, est polymérisable par polymérisation radicalaire, multifonctionnel (de préférence difonctionnel), et présente une masse moléculaire moyenne approximative d'au moins 2000.
