Abstract

A block copolymer including a block of residues of a low surface tension (meth)acrylate monomer; a block of residues of a monomer free of hydroxyl group and amine group residues; and, optionally, a third block of residues of a monomer free of hydroxyl groups and amine groups. The first, second and third blocks are made of different residues from each other and the block copolymer has a polydispersity index of less than 2.5. A controlled radical polymerization method is disclosed to make the low surface tension block copolymers. The method includes the steps of sequentially adding a first monomer composition that is free of hydroxyl groups and amine groups and a second monomer composition that includes the low surface tension monomer to a suitable atom transfer radical polymerization initiator and polymerizing the monomer compositions to form a block copolymer.

Dependent claims

A method of making a low surface tension (meth)acrylate containing block copolymer using atom transfer radical polymerization (ATRP) comprising the steps of sequentially adding a first monomer composition comprising a first radically polymerizable low surface tension (meth)acrylate monomer represented by the general formula:

wherein R1 is selected from hydrogen, methyl and ethyl, R2 is selected from the group consisting of linear, branched, cyclic, aryl and arylalkyl fluorinated hydrocarbon groups containing from 4-20 carbon atoms;
Y is a divalent linking group containing from 1 to 20 carbon atoms;
and a second monomer composition comprising one or more radically polymerizable ethylenically unsaturated monomers that are free of hydroxyl groups and amine groups, to a suitable ATRP initiator having at least one radically transferable group to form a living block copolymer, wherein said first monomer composition and second monomer composition are different from each other.

Dependencies are inferred from the claim text.
