Abstract

Novel (meth)acrylates containing fluoroalkenyl groups, of the formula (I) ##STR1## in which R represents hydrogen or methyl, PA1 n represents an integer from 2 to 6, PA1 A represents a (n+1)-valent hydrocarbon radical having 3 to 30 carbon atoms which optionally contains up to 10 oxygen atoms, and PA1 R.sup.1.sub.f and R.sup.2.sub.f independently of one another each represent a perfluoroalkyl radical having 1 to 20 carbon atoms, or PA1 R.sup.1.sub.f and R.sup.2.sub.f together form a ##STR2## bridge, in which x represents an integer from 1 to 8, and PA1 R.sup.3 represents hydrogen, fluorine, chlorine or a perfluoroalkyl radical having 1 to 20 carbon atoms, PA1 a process for their preparation, and their use for the preparation of coatings.
