| Abstract: | Hyperbranched poly(3-methyl-3-oxetanemethanol) (HBPO) was directly grafted from the surface of cellulose fibers (CF) through a surface hydroxyl group-initiated ring-opening polymerization of 3-methyl-3-oxetanemethanol (MOM). TOF–SIMS, XPS, AFM, ATR-FTIR, and TGA were utilized for characterizing the resultant HBPO-grafted cellulose fibers. The content of grafted HBPO is easily adjustable by controlling feeding dosage of the MOM. To verify the reactivity of hydroxyl groups in the grafted HBPO, poly(ε-caprolactone) (PCL) was further grafted from the HBPO-grafted cellulose surface. |
