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.

Storage Class Code

10 - Combustible liquids

WGK

WGK 3

The aim of this study was to (1) investigate the flexural strengths of three denture resins i.e. heat, photopolymerised and microwaved and how it was affected by relining with auto- and visible light-polymerised hard reliners, (2) investigate the bond strengths

An immune response to an antigen is more efficiently induced in combination with an adjuvant. Chitosan has due to documented immunostimulatory characteristics been proposed as an adjuvant candidate. However, a disadvantage with chitosan is its poor solubility at physiological pH.
