Preparation and Polymerization of 2-(Acryloyloxy)Ethyl-2-(Trimethylammonium)Ethyl Phosphate and 4-(Acryloyloxy)Butyl-2-(Trimethylammonium)Ethyl Phosphate

2-(Acryloyloxyl)ethyl-2-(trimethylammonium)ethyl phosphate (4a) and 4-(acryloyloxyl)butyl-2-(trimethylammonium)ethyl phosphate (4b) were prepared and characterized by their IR and 1H NMR spestral data and elemental analyses. 4a was homopolymerized and compolymerized with 2-hydroxyethyl acrylate, stearyl acrylate, and 1,3-dioleylacylglycerol-2-acrylate using 2,2ϵ-azoisobutyronitrile (AIBN) as initiator. Poly (4a) of the resultant polymers exhibited liquid crystalline behaviors from 118 up to 152°C observed by a polarization microscopy. Moreover, the water-soluble polymer, Poly (4a), among the resulting polymers showed a polyelectrolyte behavior from its viscosity measurement.
