Abstract
A polymer composition [composition (M)], may include 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)], the polymer (APES) being present in the composition (M) in an amount of at least 0.10 and of at most 45 wt %, with respect to the combined weight of polymer (PGA) and polymer (APES). A method of making composition (M) and method of producing a multilayer stretched product from composition (M) are also described.
