Synthesis of poly(vinyl alcohol‐graft‐hyperbranched glycerol)

ABSTRACT We report the first example of grafting hyperbranched polyglycerol onto poly(vinyl alcohol) via ring‐opening polymerisation of glycidol to prepare poly(vinyl alcohol‐graft‐hyperbranched glycerol) (P[(VA)‐g‐(hPG)]). The effects of catalyst, molecular weight of PVA, reaction temperature, water content, moles of reagent, and addition time of reagent were also investigated. P[(VA)‐g‐(hPG)] with various mole fractions of hPG were prepared and the degrees of substitution and branching were determined. P[(VA)‐g‐(hPG)] displayed decreased degree of crystallinity and also increased solubility in water, compared to PVA. P[(VA)‐g‐(hPG)] is shown to be a superior hair styling polymer with a curl retention value of 85% after 4 h. © 2017 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.
