Poly ethyl methacrylate tg
WebHennink et al. have synthesized and evaluated poly [2- (dimethylamino)ethyl methacrylate] (pDMAEMA) for gene transfer ( Fig. 4.5) [76–78]. pDMAEMA is a water-soluble cationic polymer, capable of forming compact complexes by electrostatic interaction with DNA [77]. The size of the complex depends on molecular weight. WebEthyl acrylate is an organic compound with the formula CH 2 CHCO 2 CH 2 CH 3. It is the ethyl ester of acrylic acid. It is a colourless liquid with a characteristic acrid odor. It is mainly produced for paints, textiles, and non-woven fibers. [5] It is also a reagent in the synthesis of various pharmaceutical intermediates.
