ABSTRACT Introduction: Many abuse-deterrent formulations (ADFs) rely on being crush resistant and extraction resistant in order to provide deterrence to abuse by insufflation and injection, respectively. High molecular weight polymers such as poly(ethylene oxide) are commonly used to provide this deterrence. However, these polymers suffer from slow dissolution kinetics, and are susceptible to variety of abuse conditions. Objective: This study was aimed to determine if selected superabsorbent...

Superabsorbent polymers fabricated via grafting polymerization of acrylic acid from chitosan (CTS) yields materials that suffer from poor mechanical strength. Hybridization of chitosan with cellulose (Cell) via chemical bonding using thiourea formaldehyde resin increases the flexibility of the produced hybrid (CTS/Cell). The hybridization process and post graft polymerization of acrylic acid was followed using Fourier transform infrared (FTIR). Also, the obtained structures were homogeneous and...
