In recent years, graft copolymerization has been widely used to insert
various functional groups onto polymers. In our study, methacrylic acid
monomers are grafted to polypropylene (PP) fibers to make them hydrophilic
while maintaining their mechanical properties. Experiments are designed based
on Taguchi’s method and influence of temperature, monomer concentration;
cross-linker concentration and time of reaction are investigated. Grafting of
methacrylic acid and divinyl benzene is investigated by FTIR spectra and
confirmed by SEM micrographs. Tensile strength and toughness of specimens are
measured and compared with raw fibers. Influence of grafting on the tensile
strength and toughness of fibers are measured and critical grafting degree to
maintain tensile strength and toughness of fibers is defined.
