SYNOPSIS
A new family of bioabsorbable materials suitable for biomedical applications was designed and prepared by means of blending of some available polyesters to develop new biodegradable materials tailored for different requirements. Multiphase polymer blends containing poly(d, l-lactide) (PLA), poly(e-caprolactone) (PCL), poly(d, l-lactide-co-poly(ethy1ene glycol) (PELA), poly(c-capro1actone)-co-poly(ethy1ene glycol) (PECL), and poly(P

## Abstract Blends between chitosan (CS) and gelatin (G) with various compositions (CS/G 0/100 20/80, 40/60, 60/40, 100/0 w/w) were produced as candidate materials for biomedical applications. Dehydro‐thermal crosslinking was adopted to promote the formation of amide and ester bonds between the mac
## Abstract **Summary:** The major route to convert lactic acid to high‐molecular‐weight polymers is ring‐opening polymerization of lactide. We have investigated alternative synthesis routes based on oligomerization and chain linking to produce high‐molecular‐weight thermoplastic degradable polymer
