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. WebMMA is a raw material for the manufacture of other methacrylates. These derivatives include ethyl methacrylate (EMA), butyl methacrylate (BMA) and 2-ethyl hexyl methacrylate (2-EHMA). Methacrylic acid (MAA) is used as a chemical intermediate as well as in the manufacture of coating polymers, construction chemicals and textile applications.
