These compounds are represented by the formulae (Ia) and (Ib). To prepare them, in a first stage, p-xylylene dichloride is reacted with a compound (II) to produce a compound (III) and, in a second stage, the compound (III) thus obtained is reacted with a compound of formula (IVa) or (IVb), resulting in an aqueous solution of the compound (Ia) or (Ib) respectively, the water of which is removed, if appropriate.

It has been discovered by in present invention that, compared with a fluorosurfactant having only one betaine group per molecule, a fluorosurfactant having a plurality of betaine groups per molecule is superior in its ability to undergo electrostatic interaction with other components of a fire fighting composition thereby improving the performance of the fire fighting composition. Previously known fluorosurfactants comprise only one betaine group per molecule. In contrast, the present invention provides for a fluorobetaine copolymer containing a plurality of betaine groups.
