Abstract
The present invention relates to a comb polymer comprising a main chain formed from 1-ethenyl- and/or 1-allyl-2,3,4,5,6-pentafluorobenzene monomers and polymeric side chains grafted in the para position of the pentafluorophenyl groups, in which said polymeric side chains are linked to said main chain by an oxygen atom, the molar grafting rate of polymeric side chains being greater than or equal to 50%.It also relates to a method for the preparation of such a comb polymer.
