Cationic co-polymerization between eugenol and divinilbenzene (DVB) (2%, 4%, 6%, 8%, 10% and
12%) with BF3O(C2H5)2 as a catalyst at room temperature without media under nitrogen atmosphere has been
investigated. Co-poly (eugenol sulfonate)-DVB has been synthesized by sulfonation of co-poly(eugenol-DVB). In the
sulfonation, concentrated sulfuric acid was used as the reagent and Ag2SO4 as a catalyst. Structure and
characterization of co-poly (eugenol-DVB) and Co-poly(eugenol sulfonate)-DVB were analyzed by Infra Red (IR),
Defferential Thermal Analysis) DTA and UV-Vis. Measurement of the number-average molecular weight (Mn) of
copolymer were used Ostwald capillary viscometer. The yields of co-polymerization of eugenol-DVB were solid
matter and the highest result was found on a copolymer of 10% of DVB. Its melting point was 69.33o
C. The
increasing of mole of DVB increase the number-average molecular weight (Mn) of co-poly (eugenol sulfonate)-DVB.
A copolymer of 12% of DVB gave the highest molecular weight, Mn = 2984 g/mole. Synthesized of co-poly (eugenol
sulfonate)-DVB were solid matter too and the highest result was found on a copolymer of 12% of DVB. Its melting
point was 95.5o
C.
