Abstract
Oil-repellent polymeric compositions prepared by a process which comprises: PA0 a) adding at least a radical starter and at least a perfluoropolyether to at least a molten thermoplastic polymer; PA0 b) intimately mixing the resulting composition for a time which is sufficient to obtain macroradicals from the polymer; and PA0 c) cooling the final composition to room temperature.
