Evaluation of pH-sensitive poly(2-hydroxyethyl methacrylate-co-2- (diisopropylamino)ethyl methacrylate) copolymers as drug delivery systems for potential applications in ophthalmic therapies ocular delivery of drugs
Smart polymers like pH sensitive systems can improve different pharmacological treatment. In this work the behavior of copolymers containing 2-hydroxyethyl methacrylate (HEMA) with different proportions of 2-(diisopropyl ...
Evaluation of pH-sensitive polyurethane 2-diethylaminoethyl methacrylate hybrids potentially useful for drug delivery developments
Smart sensitive polymers have been used to improve processes in drug delivery. In this article, we evaluate the behavior of polyurethane/N,N-diethylaminoethyl methacrylate hybrids (PU/DEA) as pH- responsive polymers ...
Polyurethane Poly(2-(Diethyl Amino)Ethyl Methacrylate) blend for drug delivery applications
A pH-sensitive blend of polyurethane (PU) and poly(2-(diethyl amino)ethyl methacrylate (PDEA) with good film-forming capacity was prepared from the corresponding aqueous dispersions. The polymer matrix was first characterized ...
The role of nanocrystalline cellulose on the microstructure of foamed castor-oil polyurethane nanocomposites
Nanocrystalline cellulose (CNC), obtained by sulphuric acid hydrolysis, was used to synthesize polyurethane foams (PUFs) based on a functionalized castor oil polyol and a Methylene diphenyl diiso- cyanate (MDI). Formulations ...
