Wj. Yang et al., POLYMERIZATION OF MMA INITIATED BY PVC WI TH PENDENT N,N-DIETHYLDITHIOCARBAMATE GROUPS UNDER UV-IRRADIATION, Gaodeng xuexiao huaxue xuebao, 17(9), 1996, pp. 1473-1476
The PVC containing N,N-diethyldithiocarbamate groups(PVC-SR) was prepa
red by the substitution of sodium N,N-diethyldithiocarhamate on the pa
rtial chloride of PVC and used to initiate the polymerization of MMA u
nder UV-irradiation, The effects of irradiation time, concentration of
monomer, amount and degree of functionality of PVC-SR on the polymeri
zation were investigated, The results showed that PVC-SR could efficie
ntly initiate the photopolymerization oi MMA to form crosslinked graft
copolymers which had a high grafting efficiency and a high degree of
gel.
