Abstract

The invention provides block copolymers comprising polyester linkages. These copolymers are obtained by the reaction of polyester forming precursors, RAFT agents, and radically polymerizable monomers. The invention further provides compositions comprising the block copolymers and applications thereof in various industrial areas. The invention furthermore provides a method for reducing the particle size of an active ingredient by obtaining a composition that comprises colloidal particles of the block copolymers and the active ingredient and subjecting the composition to a suitable size reduction operation. Each a, b, and R11 is described herein.
