Alternating copolymerization of fluorinated olefins (CnF2n + 1)(CH2)(m)CH=CH2 (1) and carbon monoxide was carried out using cationic Pd(II)-(R,S)-BINAPHOS complexes (2) as catalysts. To obtain polymeric products sufficiently, existence of at least two methylenes in 1 were essential (m greater than or equal to 2). The products thus obtained formed polyspiroketal (4) rather than polyketone (3), the structures being determined by solid- and solution-state NMR and IR analyses. The water contact angle was 108 degrees for a sample of 4f when it was casted on a glass surface from C6F6 solution.
