  • SOLVENTBORNE THERMOSETTING COMPOSITIONS CONTAINING COPOLYMERS OF ISOBUTYLENE TYPE MONOMERS
    Publication number: 20090023862
    Abstract: The present invention is directed to a solventborne thermosetting composition comprising: (a) a polymeric binder comprising a copolymer, said copolymer being a polymerization product of: (i) 10 to 30 percent by weight, based on the total weight of monomers used to prepare the copolymer, of a monomer having the following structure (I): wherein R1 comprises linear or branched C1 to C4 alkyl, and R2 comprises methyl, linear, cyclic or branched C1 to C20 alkyl or alkenyl; (ii) 5 to 25 percent by weight, based on the total weight of monomers used to prepare the copolymer, of a monomer having aromatic functionality; (iii) 0 to 60 percent by weight, based on the total weight of monomers used to prepare the copolymer, of an ethylenically unsaturated monomer containing secondary hydroxyl groups; and (iv) 15 to 50 percent by weight, based on the total weight of monomers used to prepare the copolymer, of an ethylenically unsaturated monomer containing primary hydroxyl groups; (b) an aminoplast curing ag
