Two types of polymer-silica nanocomposites have been prepared by undergoing free radical polymerization of 2-hydroxyethyl methacrylate (HEMA) either in the presence of HEMA-functionalized SiO 2 nanoparticles (Type 1) or during the simultaneous in situ growing of the silica phase through the acid-cat
A limitation in the use of hydrophilic poly(2hydroxyethyl methacrylate) (PHEMA) sponges as implantable devices is their inherently poor mechanical strength. This precludes proper surgical manipulation, especially in the eye where the size of the implant is usually small. In this study a new method w
Coand terpolymers containing dimethylaminoethyl methacrylate (DMAEMA) , methyl methacrylate (MMA) , and 2-hydroxyethyl methacrylate (HEMA) were prepared by solution polymerization, and characterized by dilute solution viscometry and proton and carbon-13 nuclear magnetic resonance spectroscopy. Polym
