✦ Synopsis

Three styrene derivatives bearing ¯uoroalkyl substituents in para or (meta/para) positions have been synthesized under phase-transfer-catalysis conditions. Homopolymers and copolymers with styrene have been prepared by free-radical polymerization. The monomer reactivity ratios of each monomer with styrene are determined by the Kelen±Tu È do @s method. The results show that the ¯uoroalkyl substituent does not signi®cantly affect the reactivity of the styrene double bond. Thermal and surface properties of the copolymers have been examined. Copolymers from the para-substituted styrene derivative show higher glass transition temperatures (T g ) than those obtained with the mixture of isomers. Low dispersive surface energies (11 gD S 17 mNm À1 ) are determined from contact angle data measured with the Wilhelmy plate method.
