Abstract
The invention provides methods for the preparation of multiblock copolymers, dispersions of multiblock copolymers, vesicles and micelles containing multiblock copolymers, and oxidative degradation products of multiblock copolymers.
Claims35
A method of synthesizing a block copolymer, said method comprising the steps of:
- (a) providing a first compound comprising a polymeric thiol precursor comprising a thiol bound to a protecting group;
- (b) generating a polymeric thiol from said first compound by removing said protecting group;
- and
- (c) initiating a polymerization of a second compound comprising an episulfide group with said thiol produced in step (b) thereby producing a block copolymer comprising a terminal thiol.
