A thermosetting composition that includes an ungelled copolymer composition and a crosslinking agent. The ungelled copolymer composition includes a functional group-containing copolymer that includes segments of alternating residues derived from a donor monomer composition comprising an acceptor monomer composition. The donor monomer composition includes one or both of isobutylene and diisobutylene, and the acceptor monomer composition includes acrylic monomers and monomers containing functional groups. The ungelled copolymer composition is substantially free of transition metals and Lewis acids, and the copolymer is substantially free of maleate-type monomer residues and fumarate-type monomer residues. The crosslinking agent has at least two functional groups that are reactive with the functional groups of the copolymer. The thermosetting composition may be in liquid, powder, or dispersed form and may be applied by traditional or electrocoating methods.

Thermosetting compositions containing alternating copolymers of isobutylene type monomers

A copolymer composition that includes a copolymer comprised of at least 30 mol % 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 as an acceptor monomer. The copolymer is substantially free of maleate or fumarate monomer segments and the copolymer composition is substantially free 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 agent that includes the copolymer composition as well as substrates coated with the thermosetting composition.

Alternating copolymers of isobutylene type monomers

A method of making a copolymer composition containing a copolymer, which includes the steps of (a) providing a donor monomer composition that includes an isobutylene type monomer; (b) mixing the donor monomer composition with an ethylenically unsaturated monomer composition that includes one or more ethylenically unsaturated acceptor monomers, and is substantially free of maleate type monomers and fumarate type monomers, and (c) polymerizing the mixture resulting from step (b) in the presence of a free radical polymerization initiator. The polymerization is carried out in the substantial absence of Lewis acids and/or transition metals. The isobutylene type monomer is present at a molar excess of at least 10 mol % based on the molar concentration of monomers in the ethylenically unsaturated monomer composition. The ethylenically unsaturated acceptor monomers are present in an amount of at least 15 mol % of the total monomer composition.

A process for applying two electrodeposited coatings, one on top of the other, to an electrically conductive substrate is provided. An electrically conductive first coating is applied to provide for corrosion resistance and a second polyurethane-based coating is applied to the first coating to provide chip resistance. Also, aqueous dispersions of the polyurethane coating compositions are disclosed.

A converter dolly replaces the rear wheels of a truck trailer to provide the trailer with a steering ability about its rear wheels. The converter dolly is modified to include a hydraulic actuating system, including a piston, cylinder, and pump assembly, which act upon the tongue of the converter dolly to pivot the converter dolly about a king pin. The actuation of the hydraulic system is performed by the driver of the tractor towing the trailer through a control system mounted in the tractor cab.

In accordance with the present invention, metal pigments are provided which are normally reactive with water or moisture to release hydrogen gas ('gassing') and which have been stabilized against such gassing by having their surfaces treated with an adduct of a maleinized fatty acid and/or a maleinized alpha-olefin and a polyol. Waterborne film-forming compositions which comprise an aqueous diluent medium, a film-forming polymer, and metal pigment stabilized against gassing by treatment with an adduct of a maleinized fatty acid or a maleinized alpha-olefin and a polyol are also provided.
