Block copolymers PEG-PLLA usage for modifying polymer blends

Polyscitech provides a wide array of PEG-PLLA block copolymer products (e.g. PolyVivo AK03, AK04, AK05, AK08, etc.).  Block copolymers of PLLA-PEG have recently shown promise for use in modifying the degradation rate and mechanical properties of PLLA biodegradable stents when co-blended with the PLLA.
