Novel derivatives of guar gum grafted poly
(acrylamide-co-diallyldimethyl ammonium
chloride) was discovered by Mclean et al.45 and
studied its behaviour as hydrophobic wood
resin adsorbent in paper making. Results
showed that GG-g-p(AM-co-DADMAC) act as
better polymer fixative as compared to other
commercially available fixatives. Wang et al46
and coworkers explore the potential use of
guar-grafted (poly-sodium acrylate)/Medicinal
stones as pH responsive superabsorbent
hydrogels. Characterization of these hydrogels
was done by FTIR, XRD, TGA, DTA etc
techniques. P. Chowdhury et al.47
copolymerized guar and MMA using ceric
ammonium sulphate/dextrose as a redox
initiators. Modified polymer was analysed by
FTIR and TGA techniques. Important discovery
was made by Tiwari et al 48 by preparing guar
gum–methacrylate hydrogels for in situ
fabrication of tissue engineering scaffolds.
Modification was done by reacting hydroxyl
group of guar with glycidyl methyl methacrylate
(GMA) water soluble photopolymerizable guar
gum–methacrylate (GG–MA).
