Formation of Nanoparticles of Polylactide-Containing Diblock Copolymers: Is Stereocomplexation the Driving Force?

Poly(L-lactide)-poly( epsilon -caprolactone) and poly(D-lactide)-poly( epsilon caprolactone) diblock copolymers self-assembled in tetrahydrofuran (THF) to form particles with a size roughly equal to 200 nm. The self-assembly process was driven by interactions between the poly(L-lactide) and poly(D-l...

Zusammenfassung:	Poly(L-lactide)-poly( epsilon -caprolactone) and poly(D-lactide)-poly( epsilon caprolactone) diblock copolymers self-assembled in tetrahydrofuran (THF) to form particles with a size roughly equal to 200 nm. The self-assembly process was driven by interactions between the poly(L-lactide) and poly(D-lactide) blocks. The formation of the nanoparticles was extremely low, making it possible to study the kinetics of the process and have a good control of the structure.
