摘要：

Viscosity of polyfurfuryl alcohol (PFA) and addition of hydroquinone exert a strong positive effect on grafting polyfurfuryl alcohol to cellulose fiber with H2O2/Fe2+ oxidant in an aqueous slurry at pH 2. Composition of the atmosphere and the nature of acids used to adjust pH does not influence the reaction, with the exception of phosphoric acid, which negatively influences polymer loading. Conducting the reaction in nonaqueous media inhibits grafting. K2S2O8, Ce(SO4)2, and K2Cr2O7 perform as well as H2O2/Fe2+, whereas H2O2/thiourea dioxide, H2O2/thiourea, NH4VO3, KMnO4, and KNO3 give inferior polymer loads; Mn3+/acetylacetonate and azobisisobutyronitrile are ineffective. A small improvement in polymer loading is obtained by gradual addition of the oxidant to the reaction slurry.
