Abstract:
1. A thermosetting composition comprising: (a) a first reactant comprising functional groups; (b) a crosslinking agent having at least two functional groups that are reactive with the functional groups first reactant in (a); and (c) a copolymer flow control agent comprising a copolymer comprised of at least 30 mol % of segments comprising alternating residues derived from a donor monomer selected from the group consisting of isobutylene, diisobutylene, dipentene and isoprenol, and an ethylenically unsaturated acceptor monomer, wherein said copolymer is substantially free of maleate-type monomer segments and fumarate-type monomer segments and the copolymer flow control agent is prepared in the presence of a free radical initiator and is substantially free of and prepared in the absence of Lewis acids and transition metals.
