  • Patent number: 9701766
    Abstract: The present invention pertains to a process for the manufacture of a grafted fluorinated polymer comprising at least one grafted side chain comprising one or more glycosidic recurring units [polymer (F)], said process comprising polymerizing: vinylidene fluoride (VDF), optionally, one or more other fluorinated monomers [monomers (F)], and optionally, one or more (meth)acrylic monomers [monomers (MA)], in the presence of at least one polysaccharide derivative [derivative (P)], said polysaccharide derivative having a dynamic viscosity of less than 15 mPa×s, as measured according to ASTM D445 at 20° C. in an aqueous solution at a concentration of 2% by weight, and by further providing novel polymers (F) as defined above.

  • Patent number: 9676909
    Abstract: The present invention pertains to a process for the manufacture of a grafted fluoropolymer [polymer (Fg)], said process comprising reacting: A) at least one fluoropolymer comprising at least one functional group selected from the group consisting of a hydroxyl group and a carboxylic acid group [polymer (F)], B) at least one polyoxyalkylene (POA) of formula (I): RB—(CH2—O)x—(CH2CHRAO)n—(CH2—O)x?—RC, wherein at least one of RB and RC is a reactive group comprising at least one heteroatom selected from oxygen and nitrogen different from the hydroxyl group, the remaining, if any, being a —[O]z—CH3 alkyl group, wherein z is 0 or 1, RA is a hydrogen atom or a C1-C5 alkyl group, x and x?, equal to or different from each other, are independently 0 or 1, and n is an integer comprised between 2 and 1000, preferably between 5 and 200, C) optionally, in the presence of at least one catalyst, and D) optionally, in the presence of at least one organic solvent (S).
