Abstract

Degradation rates of a copolymeric PLGA can be controlled by varying the constituent amount in the copolymer. In the present study we have made an attempt to utilize microwave irradiation to blend PLLA and PGA in different concentrations. FTIR, NMR and DSC measurements clearly show the blending and cross-linking between the constituents.

Main findings

The study used microwave irradiation to blend PLLA and PGA at different concentrations. FTIR, NMR, and DSC measurements indicated blending and cross-linking between the constituents.

Outcomes measured

Blending of PLLA and PGA
Cross-linking between constituents (as indicated by FTIR, NMR, DSC)
