GRAFTING OF ACRYLONITRILE ONTO CELLULOSE BY USING MANGANESE(IV)AS INITIATOR
以四价锰为引发剂纤维素与丙烯腈接枝共聚的研究

A new method of grafting acrylonitrile onto viscose filament with manganese (IV) as initiator has been developed under proper conditions, higher graft increment could be obtained by keeping homopolymerization at its minimum. The results obtained from X-ray diffraction, microscopic and SEM studies showed that copolymerization mainly occurs in low ordered region.
