<p>A compound of formula (I), wherein R1 and R2 are independently selected from saturated fluorocarbon substituted side chains, such as NR5(CH2)nCmF2m+1, O(CH2)nCmF2m+1, S(CH2)nCmF2m+1, NR5S(O)2(CH2)pCmF2m+1, or CR5¢CO2(CH2)nCmF2m+1!2, where R5 is hydrogen or alkyl, n and m are independently an integer of 1-12, and p is 0 or an integer of 1-12, R3 is an unsaturated moiety which may be polymerised, and X is O, S or NR4 where R4 is hydrogen or alkyl, as well as methods for the preparation of these compounds. Compounds of formula (I) are useful monomers in the preparation of oil- and water-repellent polymers.</p> |
