摘要： A method for extending the gelation time of an oxidized polysaccharide to react with a water-dispersible, multi-arm amine to form a hydrogel is disclosed. The extension of the gelation time is accomplished by using a chemical additive. The method also extends the time for the hydrogel to become tack-free, and may also be used to decrease the degradation time of the hydrogel. The chemical additive reacts with the functional groups of the oxidized polysaccharide or the water-dispersible, multi-arm amine, thereby reducing the number of groups available for crosslinking. The use of the resulting hydrogel for medical and veterinary applications is described.

摘要： Temperature switchable pressure sensitive adhesives comprising an elastomer and a crystallizable abietic acid derivative as tackifier are described. These pressure sensitive adhesives exhibit a sharp reduction in peel strength when the temperature is raised above the switching temperature. The adhesive properties of these adhesives may be readily tuned by adjusting the ratio of the elastomer and the crystallizable tackifier, and by altering the crystallizabe group on the tackifier. The temperature switchable pressure sensitive adhesives have use in medical, consumer, and industrial applications.
