Patent

CA 2665846

Biocompatible, bioresorbable polymers comprising a plurality of monomeric repeating units containing an amide group, wherein said amide groups are N-substituted and the N-substituent and degree of N-substitution is effective to lower the melt viscosity, the solution viscosity, or both, compared to the same polymer without N-substitution.

L'invention concerne des polymères biocompatibles, biorésorbables comprenant une pluralité de motifs monomères répétés contenant un groupe amide, lesdits groupes amides étant N-substitués et les N-substituants ainsi que le degré de N-substitution étant efficaces pour abaisser la viscosité à l'état fondu, la viscosité en solution, ou les deux, par comparaison avec le même polymère sans N-substitution.
