Abstract

Procedeu pentru tratarea unui polimer obtinut prin polimerizarea în faza de vapori, caracterizat prin aceea ca se evacueazp polimerul solid din reactor, împreuna cu gazele de evacuare, fara o scadere substantiala a presiunii într-o zona de postpolimerizare, în care se introduce o cantitate suplimentara de monomer si în care are loc o polimerizare adiabatica iar polimerul este topit, sub actiunea caldurii, provenite în urma polimerizarii adiabatice, urmata de o încalzire din exterior si evacuarea polimerului topit din forma de postpolimerizare. Process for treating a polymer obtained by vapor phase polymerization, characterized in that the solid polymer in the reactor is discharged together with the exhaust gases without a substantial decrease of the pressure in a postpolymerization zone in which an additional amount of the monomer and wherein the adiabatic polymerization occurs and the polymer is melted under the action of heat resulting from the adiabatic polymerization followed by an external heating and the evacuation of the molten polymer from the post-polymerization form.
