- •
PEO-b-PCL copolymers with low dispersity (ĐM < 1.1) can be obtained by a kinetically controlled synthesis.
- •
Purification of SnOct2 catalyst is crucial for the kinetically controlled polymerization of ɛ-CL.
- •
Low dispersity of PEO-b-PCL enables to control its self-assembly into uniform mesoscale polymersomes.
