Abstract
Invnetia se refera la un procedeu de obtinere a poliacetatului de vinil cu grad de ramificare mic si masa moleculara mare, prin polimerizarea în atmosfera de azot a acetatului de vinil cu o concentratie de 7,1 ... 7,5 mol/l într-un amestec din 5 volume metanol si un volum apa sub actiunea sistemului redox persulfat de amoniu - acid L - ascorbic, la 20 ... 40 grade C.The invention relates to a process for obtaining a low branched vinyl polyacetate and a high molecular weight by polymerizing in the nitrogen atmosphere of vinyl acetate with a concentration of 7.1 ... 7.5 mol / a mixture of 5 volumes of methanol and a volume of water under the action of the redox persulfate system of L - ascorbic acid at 20 to 40 degrees C.
