Development of photocrosslinked polyacrylic acid hydrogel as an adhesive for dermatological patches: Involvement of formulation factors in physical properties and pharmacological effects

Photocrosslinked polyacrylic acid hydrogel is a promising candidate adhesive for dermatological patches. In this study, we investigated the effects of the composition and molecular weight of the polymer on the characteristics of the hydrogel. Several photocrosslinkable polymers with different photocrosslinkable moieties or molecular weights were prepared, and various physical properties were measured. Differences in photocrosslinkable...
