Disclosed is a fluorine-containing oligomer comprising a copolymer of a fluoroalkyl alcohol (meth)acrylic acid derivative of the formula: C


Disclosed is a fluorine-containing copolymer comprising a copolymer of a polyfluoroalkyl alcohol (meth)acrylic acid derivative represented by the general formula: wherein R is a hydrogen atom or a methyl group, n is an integer of 1 to 6, a is an integer of 1 to 4, b is an integer of 1 to 3, and c is an integer of 1 to 3, and styrene or a derivative thereof; and also disclosed is a surface modifier comprising the fluorine-containing copolymer as an active ingredient. When the fluorine-containing copolymer is used as an active ingredient of a surface modifier, the heat resistance of the surface modifier can be further improved.

Disclosed is a rubber metal laminate comprising metal, an adhesive layer and a perfluoroelastomer layer, the perfluoroelastomer layer being formed from a vulcanizate layer of a blend comprising 2 to 10 parts by weight of a vinylidene fluoride-chlorotrifluoroethylene copolymer, based on 100 parts by weight of a perfluoroelastomer. The rubber metal laminate of the present invention can effectively improve the interlayer adhesion of the perfluoroelastomer to the metal and pockmarked surface (the state that crater-like irregularity is formed) of the perfluoroelastomer layer laminated on the metal.
