Characterization of cotton–polystyrene graft copolymers

Abstract
Characterization of cotton–polystyrene graft copolymers prepared by ceric ion initiation is reported. Various techniques studied include moisture sorption, solubility in cupriethylenediamine (CED), infrared spectra, differential thermal analysis (DTA), electron micrographs and X‐ray diffractograms, which point to the existence of true grafting. The graft copolymers showed a slight fall in breaking load and improved resistance to wetting.
