    Abstract: Medium and high molecular weight polyester polymers are prepared in syrup form from an ester oligomer. The oligomer is converted to the polymer by polycondensation at elevated pressure and elevated temperature in a nonreactive carrier capable of forming an azeotrope with water. The ester oligomerization or polycondensation reactions desirably are monitored using a non-viscometric technique. The process has a rapid cycle time. The syrup contains the polymer and nonreactive carrier, and may more conveniently be used to make initially non-solid products such as polyester coatings than is the case when employing pelletized solid polyester resins.

    Abstract: Un artículo revestido que incluye un sustrato de compuesto; y un sistema de revestimiento al sustrato. El sistema de revestimiento incluye un composición de revestimiento que funciona con pegamento aplicada al sustrato, y una composición de revestimiento con base en agua, distinta de la composición de revestimiento funcional con pegamento, aplicada al revestimiento con base en pegamento, entre las composiciones. También se proporciona un método que incluye los pasos de: proporcionar un sustrato de compuesto de cemento; aplicar una composición de revestimiento funcional con pegamento al sustrato; y aplicar una composición de revestimiento con base en agua, distinta de la composición de revestimiento funcional con pegamento, al revestimiento con base en pegamento. La composición con base en agua utilizada en este método preferiblemente comprende un polímero que tiene uno o más grupos funcionales que pueden reaccionar con un revestimiento con base en pegamento para promover la adhesión entre las composiciones.

    Abstract: A low viscosity blocked isocyanate solution can be made by reacting together a polymeric isocyanato compound and propylene glycol, or a polymeric primary or secondary amine and propyl carbonate. The resulting beta-hydroxypropyl urethane polymer can be combined with propylene glycol monomethyl ether as a reducing solvent to form a pourable high-solids solution with good flow properties at room temperature. The solution has lower viscosity than is obtained using ethylene glycol as a blocking agent or using several non-HAPS reducing solvents that are similar to propylene glycol monomethyl ether. The solution can readily be combined with electrodepositable paint ingredients to form a curable coating composition.
