<p>A composition including a block copolymer that includes a first block of residues of a first low surface tension (meth)acrylate monomer, a second block containing residues of a second radically polymerizable ethylenically unsaturated monomer that is free of hydroxyl groups and amine groups, and, optionally, a third block containing residues of a third radically polymerizable ethylenically unsaturated monomer that is free of hydroxyl groups and amine groups. The block copolymer is prepared by controlled radical polymerization and has a polydispersity index of less than 2.5. The composition may further include a first reactant having functional groups and a second reactant having functional groups that are coreactive with the functional groups of the first reactant. The composition may be a thermosetting composition where the block copolymer is present as a flow control agent.</p> |
