摘要： A roll cover, in particular for a roll for treating a paper, cardboard, tissue or other fibrous web in a machine for producing and/or finishing said web and, in particular, for a calender roll and/or a guide roll, comprises at least one layer which forms the outer surface of the roll cover with a thickness of at least 2 mm, wherein the at least one layer is formed from at least one polymer or contains a matrix made from at least one polymer, wherein the at least one polymer has covalently bonded partly fluorinated or perfluorinated groups, wherein the partly fluorinated or perfluorinated groups are distributed uniformly over the volume of the roll cover. The roll cover preferably comprises a matrix which is formed from the at least one polymer, wherein particles made from a polymer which has partly fluorinated or perfluorinated groups are embedded into the matrix, wherein at least part of the particles are connected to the matrix polymer directly or covalently via a spacer group.
