Abstract
SE PREPARA CLORURO DE POLIVINILO POR POLIMERIZACION DE SUSPENSION DE UNA CARGA MONOMERICA DE CLORURO DE VINILO DISPERSADO Y SUSPENDIDO EN UN MEDIO ACUOSO MIENTRAS SE AGITA LA SUSPENSION. UN ALCOHOL POLIVINILO SAPONIFICADO PARCIALMENTE SOLUBLE EN ACEITE SE AÑADE A LA CARGA MONOMERICA COMO UN DISPERSANTE AL PRINCIPIO DE LA POLIMERIZACION. UN ALCOHOL POLIVINILO SAPONIFICADO PARCIALMENTE SOLUBLE EN AGUA Y/O UNA HIDROXIPROPILMETILO CELULOSA ES CONTINUAMENTE AÑADIDA COMO UN AGENTE SUSPENDEDOR DESDE EL PRINCIPIO DE LA POLIMERIZACION. EL AGENTE SUSPENDEDOR ES ENTERAMENTE AÑADIDO MIENTRAS LA PROPORCION DE POLIMERIZACION ESTA ENTRE UN 5-50%. LA FUERZA DE AGITACION APLICADA A LA SUSPENSION ACUOSA ES 50-110 KG M/S TON MIENTRAS EL AGENTE SUSPENDEDOR ESTA SIENDO AÑADIDO, E INCREMENTADO POR ENCIMA DE 110 KG M/S TON DESPUES DE COMPLETAR LA ADICION. EL POLIMERO RESULTANTE TIENE UNA ALTA DENSIDAD DE MASA Y UNA DISTRIBUCION DE TAMAÑO DE PARTICULA INTENSA Y ES SUSCEPTIBLE A LA EXTRUSION.
