19 Claims

1. A polymer composition [composition (M)], said composition (M) comprising:

i) at least one polyglycolic acid polymer [polymer (PGA)], wherein polymer (PGA) is a branched polyglycolic acid polymer [polymer (b-PGA)]; and

ii) at least one amorphous polyester [polymer (APES)], said polymer (APES) being present in the composition (M) in an amount of at least 0.10 wt percent and of at most 45 wt percent, with respect to the combined weight of polymer (PGA) and polymer (APES), wherein the polymer (APES) has a heat of fusion of less than 2.0 J/g as measured according to ASTM D3418.
