Abstract
Inventia se refera la un procedeu de obtinere a poliacetatului de vinil cu grad de ramificare mic si masa moleculara mare, prin polimerizarea acetatului de vinil cu o concentratie de 7 ... 7,5 mol/l într-un amestec din 5 vol metanol si un volum apa, sub actiunea sistemului redox persulfat de amoniu - N,N-dimetilaminopropiontitril în cantitati catalitice la 30 ... 50 grade C.The invention relates to a process for obtaining low-branched vinyl acetate and high molecular weight by polymerizing vinyl acetate with a concentration of 7 ... 7.5 mol / l in a mixture of 5 volumes of methanol and a volume of water under the action of the N, N-dimethylaminopropionitrile redox persulfate system in catalytic amounts at 30 to 50 degrees C.
