Abstract
Vesicles formed from a block copolymer comprising at least one (poly)2-C1-3alkyl-2-oxazoline block and at least one polybutadiene block; and membranes comprising such vesicles. Block copolymers comprising at least one (poly)2-C1-3alkyl-2-oxazoline block and at least one polybutadiene block, provided that the copolymer is not the diblock copolymer consisting of 40 butadiene units and 190 2-methyl-2-oxazoline units terminated by a hydroxy group, are novel, and also form part of the invention.
