Star-shaped architecture degradation

In this study, lactide was polymerized by Sn-oct in the presence of polyfunctional alcohols such as glycerol or pentaerythritol. The resulting PLA had multi-armed chains to yield a star-shaped architecture. The microstructure, thermal properties, and degradation behaviour were studied to compare the effect of the different architecture, linear PLA with starshaped one. In addition, it was very beneficial to study the effect of various chain end groups on the thermal and hydrolytic stability of this multi-armed PLA. Therefore, OH terminal groups of PLA were converted into Cl, NH2 or COOH groups. [Pg.224]

The star-shaped architecture was also applied to poly(glycolide-co-e-caprolactone) (PGCL) for developing a flexible monofilament suture. The microstructure, thermal properties, and degradation rate of linear and star-shaped PGCL was studied in terms of the different chain structure. Additionally, the mechanical properties of drawn fibres made of linear and star-shaped PGCL were compared. [Pg.224]
