General description

PEMA is known to exhibit biocompatibility and in vivo stability in its various use in implants and medical devices. Sorption of low solubility gases in PEMA was observed to be comparatively lower that polymers with high transition temperature.

Application

Poly(ethyl methacrylate) (PEMA) may be used to prepare polymer blends with polystyrene using organically modified clay as emulsifier.
