    Abstract

    A new class of gels obtained from aqueous solutions of hydroxypropylcellulose partially esterified with methacryloylchloride was prepared by UV crosslinking. Measurements of swelling degree and the elastic properties of samples having different esterification degree were treated according to the theory developed for semirigid chains: the values of the ? (number of elastically active chains) and ? (polymer-solvent interaction parameter) were calculated and used to interpret some experimental behaviours. Moreover, thermosensitive response was evidenced and related to the trend of the enthalpic and entropic components of ? as functions of temperature.
