| 摘要 |
<p>This invention involves a composition composed of a homopolymer of vinyl ethylene carbonate or a copolymer of vinyl ethylene carbonate, which is further reacted with ammonia, a primary alkyl amine, or an amino alcohol. The resulting compound, which is a polymer containing both carbamate and hydroxyl groups is then mixed with an aminoplast, coated on a substrate and cured to form a crosslinked coating. In addition, the polymer containing both hydroxyl and carbamate functional groups can be further reacted with either an anhydride or a monofunctional isocyanate, resulting in a copolymer containing only carbamate functional groups. This copolymer is mixed with an aminoplast, coated on a substrate and cured to form a crosslinked coating.</p> |
