1. A method of preparing an adhesive composition having an optimized degree of adhesion, comprising:

  • (a) preparing a plurality of compositions each comprised of a hydrophilic polymer having a glass transition temperature Tg pol admixed with a plasticizer miscible therewith and having a glass transition temperature Tg pl and capable of covalently or noncovalently crosslinking the hydrophilic polymer, wherein the weight fraction of the hydrophilic polymer in each composition is wpol, and the weight fraction of the plasticizer in each composition is wpl;

    (b) calculating predicted glass temperatures Tg predicted for each composition using the Fox equation (1)
