Abstract
A method for preparation of block copolymeric nanoparticles is disclosed. The method is a single-step preparation in which block copolymeric nanoparticles are produced directly from a solution of crosslinkable block copolymer in a carrier medium. The block copolymeric nanoparticles thus formed have at least one crosslinked polymeric phase.
Claims10
A method for the preparation of plural block copolymeric nanoparticles, said method comprising the steps of:
- (a) forming a solution by dissolving a crosslinkable block copolymer in a carrier medium;
- (b) combining at least one crosslinking agent with said solution;
- (e) reacting said crosslinking agent with said crosslinkable block copolymer;
- and
- (f) optionally, isolating said block copolymeric nanoparticles;
- wherein:
- (i) said crosslinkable block copolymer comprises at least one crosslinkable block and at least one non-crosslinkable block;
- and
- (ii) said crosslinkable block comprises at least one crosslinkable group, or at least one group modifiable to produce a crosslinkable group.
