Study of the copolymerization of fluorinated acrylic monomers with morpholinoethyl methacrylate

The copolymerization of 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodecyl acrylate (AC8), methacrylate (MAC8) and alpha-acetoxyacrylate (alpha AC8) with morpholineothyl methacrylate (MEMA) is presented. For these three systems, the values of the reactivity ratios (r(i)) of both comonomers were determined by means of four methods (Jaacks, Macret, Fineman-Ross and Tidwell-Mortimer) usually used, and these results were compared. In each case, the copolymer obtained exhibits a structure with a higher content of the fluorinated base unit. A reactivity scale in the radical copolymerization with MEMA is proposed and shows that alpha AC8 and MAC8 are more reactive than AC8, contrary to their homopolymerization behaviour. An explanation of such a tendency was suggested taking into account the Q-e scheme of Alfrey and Price of hydrocarbon homologues.
