US Classification:

525227, 525276, 525199, 525280, 5253312, 5253262, 525254, 5253265, 525294, 525295, 526169, 526170, 526171, 526172

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.

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.

US Classification:

525/088000, 525/09200R, 525/09200H, 525/093000

Abstract:

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.
