Direct radiation grafting of acrylic acid to nylon-6 fabric and the behaviour of the resulting graft copolymer

摘要: The role of certain cations as homopolymer inhibitors in the direct radiation grafting acrylic acid to nylon-6 fabric was investigated. solution methanol and water at a ratio 30 : 70 vol%. maximum graft yield obtained 0.08 wt% when using Fe 2+ 0.7% for 3+ . In addition, with latter ion higher than that former. Moreover, presence Na + K salts concentrations low 0.1 caused an increase yield. hydrophilic properties investigated indicated absorption after 9 days increased by 44 times poly(acrylic acid) 166% This became 123 times, this copolymer transformed sodium salt. These ratios 105 490 corresponding recrystallized forms, respectively. A study made gain better understanding observed super SEM DSC analysis. micrographs formation large pores dendritic structure. showed decrease both heat fusion melting point. grafted noticeable affinity different dyestuffs.
