Abstract: Quality control process of halogenated vinylic polymer latex during radical polymerisation in an aq. emulsion of halogenated vinyl monomers. A light beam is shone through the aq. emulsion and the light from 100-2500 nm reflected by the polymer particles in the latex are sent to a near IR spectrophotometer. The reflected light is measured at specific wavelengths within the given band and the results correlated with specific properties of the latex using correlation equations stored in the memory. The measured values are input into the memory and the controlled property is calculated. Also claimed is a device used for the claimed process.

Abstract: Procedimiento de control de calidad de látex de polímeros vinílicos halogenados durante la polimerizacion en emulsion acuosa en el que se hace incidir una radiacion luminosa directamente sobre la emulsion acuosa, se capta y se transmite, a un espectrofotometro de infrarrojo proximo, la luz difusa reflejada por las partículas polímeras del látex en la banda espectral situada entre 1100 y 2500 nm y se mide la luz difusa reflejada de ciertas longitudes de onda especificas relacionadas por ecuaciones de correlacion con propiedades específicas del látex controlado. Dispositivo para el control de calidad de látex en un reactor durante la polimerizacion que comprende esencialmente una sonda de medida dispuesta en el reactor, un enlace optico de dicha sonda con un espectrofotomero de infrarrojo proximo provisto de medios para emitir la luz y para captar la luz difusa reflejada y de un ordenador que tienen en memoria las ecuaciones de correlacion.

Abstract: Procédé de contrôle de la qualité de latex de polyméres vinyliques halogénés en cours de polymérisation en émulsion aqueuse dans lequel on émet un rayonnement lumineux directement dans l'émulusion acqueuse, on capte et on transmet à un spectrophotomètre proche infrarouge la lumière diffuse réfléchie par les particules polymériques du latex dans la bande spectrale située entre 1100 et 2500 nm et on la mesure à des longueurs d'onde spécifiques reliées par des équations de corrélation à des propriétés spécifiques du latex contrôlé. Dispositif pour le contrôle de la qualité de latex dans un réacteur en cours de polymérisation comprenant essentiellement une sonde de mesure disposée dans le réacteur, une liaison optique de ladite sonde avec un spectrophomètre proche infrarouge pourvu de moyens pour émettre de la lumière et pour capter la lumière diffuse réfléchie et d'un ordinateur ayant en mémoire les équations de corrélation.
