Abstract

La presente invencion se refiere a un proceso acuoso, continuo, de flujo horizontal, de direcciones multiples para la polimerizacion por radicales libresde monomeros para su posterior procesamiento a polímeros deshidratados que comprende los pasosde : a) preparar una solucion acuosa de uno o más monomeroshidrosolubles teniendo una concentracion de aproximadamente 5 a aproximadamente 80% en peso; b) alimentar de manera continua la solucion a un reactor alineadohorizontalmente que tenga unacavida d interior, un alojamiento exterior, un extremo de entrada, un extremo de salida y un dispositivo de transporte y mezcladentro de la cavidad interior; c) mezclar y contramezclar la solucion a medida que es transportada desde el extremo deentrada hac ia el extremo de salida através de la cavidad interior del reactor, mediante un dispositivo bajo condiciones de polimerizacion por radicales libres; y d) retirar de manera continua unasolucion polimérica por el extremo de salida delreactor. El proce so permite una polimerizacion eficiente de los monomeros en una solucion acuosa, en presenciade un catalizador de radicales libres, mediante un contramezclado. Utilizando este proceso, se obtienen polímeros hidrosolubles con unpeso molecular deaprox imadamente 3.000 a 30.000.000 y de preferencia de aproximadamente 500.000 a 10.000.000.
