摘要： Disclosed herein are methods for synthesizing oligomer mixtures with one or more moieties capable of forming a multi-hydrogen bonding dimer. The method comprises the steps of providing certain intermediate reaction products; adding a polyol component to the intermediate reaction product to yield an oligomer mixture comprising one or more multi-hydrogen bonding groups; and further reacting the mixture with certain isocyanate-reactive compounds to yield a multi-hydrogen bonding oligomer, wherein solvents comprise less than 50% of the total by weight of all reagents used in the synthesis of the multi-hydrogen bonding oligomer. Preferably, such methods involve no separation, distillation, or isolation of any intermediate product, and as such, they are particularly useful for a continuous or one-pot synthesis.

摘要： The present invention provides an anti-corrosion composition comprising an inorganic ion-exchanger and a waterborne resin, wherein a substrate exposed to a halide-containing environment and having the anti-corrosion composition applied thereto has a reduced level of corrosion compared to the substrate exposed to the halide-containing environment without the anti-corrosion composition being applied. The inventive waterborne anti-corrosion composition may find use on substrates such as automotive vehicles, bridges, cranes, superstructures, offshore oil & gas rigs, pipes, tanks, ships, barges, boats, aircraft, concrete, and masonry that are exposed to halide-containing environments.
