Abstract

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 α‐acetoxyacrylate (αAC8) with morpholinoethyl 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 αAC8 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.
