Abstract
The present application discloses biodegradable polymers, to porous and other materials comprising such polymers, and to various medical uses of such materials, including use as a scaffold for supporting cell adhesion or the in-growth for regeneration of tissue. The polymer is of the formula A-O—(CHRCHRO)—B wherein A is a poly(lactide-co-glycolide) residue, the molar ratio of (i) lactide units [—CH(CH)—COO—] and (ii) glycolide units [—CH—COO—] in the poly(lactide-co-glycolide) residue being in the range of 80:20 to 10:90, B is either a poly(lactide-co-glycolide) residue or hydrogen, C-alkyl or hydroxy protecting groups, one of Rand Ris hydrogen or methyl, and the other is hydrogen, n is 10-1000, the molar ratio of (iii) polyalkylene glycol units [—(CHRCHRO)—] to the combined amount of (i) lactide units and (ii) glycolide units in the poly(lactide-co-glycolide) residue(s) is at the most 14:86, and the molecular weight of the copolymer is at least 20,000 g/mol.
