Abstract
Procedimiento para reducir la incrustación de los reactores utilizados en la polimerización en dispersión acuosa de monómeros vinílicos halogenados, caracterizado porque se polimerizan monómeros vinílicos halogenados en dispersión acuosa, con intervención de iniciadores de polimerización por radicales y de agentes emulsionantes o dispersantes usuales, en presencia de una cantidad eficaz de cationes de piridinio como inhibidores de incrustación.
