Abstract
Se describen polímeros dendríticos con una mayor amplificacion y funcionalidad interior. Estos polímeros dendríticos se realizan con el uso de una química de apertura de anillos reactiva y rápida (u otras reacciones rápidas) en combinacion con el uso de reactivos de celdas de ramas de manera controlada para construir de manera rápida y precisa estructuras de dendrímeros, generacion por generacion, con estructuras precisas con una química más limpia, generalmente productos individuales, menores excesos de reactivos, niveles inferiores de dilucion, método de capacidad superior, graduacion más fácil para dimensiones comerciales, nuevos rangos de materiales y menores costos. La composicion del dendrímero preparada poseen una funcionalidad interna novedosa, mayor estabilidad; por ejemplo la estabilidad térmica y ninguna o poca reaccion inversa de Michael, y alcanza densidades de superficie de encapsulamiento en generaciones inferiores. Inesperadamente, esta reacciones de reactivos de celdas de rama polifuncionales con superficies polifuncionales no crean materiales gelificados. Estos polímeros dendríticos son utiles como desemulsificadores para emulsiones de aceite/agua, agentes de resistencia a la humedad en la fabricacion de papel, secuestradores de protones, estándar de calibracion para microscopio de electrones, preparacion de membranas selectivas por tamano, y agentes para modificar la viscosidad en las formulaciones acuosas, como por ejemplo pintura. Cuando estos polímeros dendríticos poseen un material transportador asociado con su superficie y/o interior, entonces estos dendríticos poseen propiedades adicionales en virtud de las características unicas del polímero dendrítico.Dendritic polymers with greater amplification and interior functionality are described. These dendritic polymers are made with the use of a reactive and rapid ring opening chemistry (or other rapid reactions) in combination with the use of branch cell reagents in a controlled manner to quickly and accurately build dendrimer structures, generation by generation, with precise structures with cleaner chemistry, usually individual products, lower excess reagents, lower dilution levels, higher capacity method, easier graduation for commercial dimensions, new material ranges and lower costs. The composition of the prepared dendrimer has a novel internal functionality, greater stability; for example the thermal stability and no or little inverse reaction of Michael, and reaches encapsulation surface densities in lower generations. Unexpectedly, this reactions of polyfunctional branch cell reagents with polyfunctional surfaces do not create gelled materials. These dendritic polymers are useful as demulsifiers for oil / water emulsions, moisture resistance agents in papermaking, proton sequestrators, calibration standard for electron microscopy, preparation of selective membranes per size, and agents for modifying the viscosity in aqueous formulations, such as paint. When these dendritic polymers possess a carrier material associated with their surface and / or interior, then these dendritic possess additional properties by virtue of the unique characteristics of the dendritic polymer.
