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 atmospheric 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: A primer/topcoat coil coating system employs crosslinkable branched hydroxyl-functional polyester-imide resins derived or derivable from a symmetric aromatic imide triol and a diacid or acid-producing derivative. The primer resin has a hydroxyl number greater than about 90 but not more than about 215, the topcoat resin has a hydroxyl number greater than about 100 but not more than about 215, and the primer and topcoat can each be hardened in 30 seconds or less to provide a coating having at least 0T flexibility with no tape off and at least 2H pencil hardness.

Abstract: Se preparan polímeros de poliéster de peso molecular medio y alto en forma de jarabe a partir de un oligómero de éster. El oligómero es convertido al polímero mediante policondensación a presión atmosférica y temperatura elevada en un portador no reactivo capaz de formar un azeótropo con agua. Las reacciones de oligomerización de éster o policondensación son monitoreadas deseablemente usando una técnica no viscométrica. El proceso tiene un tiempo de ciclo rápido. El jarabe contiene el polímero y portador no reactivo, y puede usarse más convenientemente para hacer productos no sólidos inicialmente, tales como recubrimientos de poliéster que es el caso cuando se emplean resinas de poliéster sólidas pelletizadas.
