ALTERNATING COPOLYMERS OF ISOBUTYLENE TYPE MONOMERS

摘要

A copolymer composition that includes a copolymer comprised of at least 30 m ol % of residues having the following alternating residues from a donor monomer and from an acceptor monomer. The copolymer contains at least 15 mol % of an isobutylene type donor monomer and at least 15 mol % of an acrylic monomer a s an acceptor monomer. The copolymer is substantially free of maleate or fumarate monomer segments and the copolymer composition is substantially fre e of Lewis acids and transition metals. Also disclosed is a thermosetting composition that includes a reactant comprising functional groups, a crosslinking agent having at least two functional groups that are reactive with the functional groups first reactant, and a copolymer flow control agen t that includes the copolymer composition as well as substrates coated with th e thermosetting composition.
