THE AQUEOUS radical polymerization of hexyl acrylate (HA), hexyl methacrylate (HMA), dodecyl methacrylate (DMA) and stearyl methacrylate (SMA) using 2,2'-Azobis(2-methylpropionamidine) dihydrochloride (V50) as initiator is reported. Only two monomers were polymerized, HA and HMA with conversion of 10 and 13 %, respectively. For DMA and SMA no polymers were found. To increase the polymerization ability of these monomers, beta-Cycodextrin (CD) was used to complex the monomers forming the water soluble host-guest monomer complex. The CD-monomer complex was performed in two different solvents namely, chloroform and water followed by polymerization. H-1 NMR proved the formation of the CD-monomer host-guest complex. The polymerization yield was found to be 45, 41, 33 and 10 % for HA, HMA, DMA, and SMA, respectively for complexes prepared in chloroform, while for complexes prepared in water, the conversions of polymerization found to be 58, 56, 50, and 45 % for HA, HMA, DMA, and SMA, respectively. The same results were obtained, when the above complexed monomers were copolymerized with diallydimethyl ammonium chloride (DADMAC) even using conventional radical polymerization or controlled radical polymerization.
