An
attempt was made by Behari et al.to
crosslink environmental friendly monomer Nvinyl
formamide on guar gum by using
brominated /ascorbic acid initiating system.
GG-g-NVF novel grafted copolymer was
characterized by IR-spectroscopic, XRD,
TGA/DSC thermal techniques. I.Gliko-Kabir et
al.Crosslinked GG with glutaraldehyde (GA).
Physiochemical changes or grafting efficiency
of modified gum were characterized by
differential scanning calorimetry (DSC),
thermal gravimetric analysis (TGA) and wideangle
X-ray diffraction (WAXD). Cunha et al.
copolymerized GG with glutaraldehyde to
obtain a high molecular weight novel hydrogel
which has potential candidate for biomaterials.
