ABSTRACT:
The present invention is directed to a copolymer that includes a first radically polymerizable low surface tension (meth)acrylate monomer and one or more other radically polymerizable ethylenically unsaturated monomers. The copolymer has a polydispersity index of less than 2.5. The present invention further includes a controlled radical polymerization method to make the above described low surface tension containing copolymers. The method includes the steps of adding a first radically polymerizable low surface tension (meth)acrylate monomer and one or more other radically polymerizable ethylenically unsaturated monomers to a solution containing a suitable atom transfer radical polymerization (ATRP) initiator.
