    摘要： 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.

    摘要： A thermosetting composition that includes a first reactant having functional groups; a second reactant having functional groups coreactive with the functional groups of the first reactant; and a block copolymer flow control agent. The block copolymer includes a first block made up of residues of a radically polymerizable fluoroalkyl(meth)acrylate monomer, a second block made up of residues of a second radically polymerizable ethylenically unsaturated monomer, and optionally a third block made up of residues of a third radically polymerizable ethylenically unsaturated monomer. 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. Also disclosed is a method of coating a substrate including the steps of applying the present thermosetting composition to the substrate; coalescing the thermosetting composition to form a substantially continuous film; and curing said thermosetting composition by the application of heat.
