    摘要: Macromonomeric (meth-)acrylate esters, having fluoroalkyl groups are disclosed. The esters have the general formula ##STR1## wherein R.sup.1 is the same or different and represents a hydrogen or fluorine groupR.sup.2 is the same or different and represents a hydrogen or methyl group,a has a value of 0, 1, 2, 3 or 4,c has a value of 2, 3 or 4,b has an average value of 2 to 30n has an average value of 4 to 12 andm has an average value of 3 to 14.The products can be used in dentistry, preferably as relining material for dental prostheses. The esters have a lower solubility and a higher mechanical strength when cured and adhere to already cured poly(methyl methacrylate).
