Disclosed are polymethacrylic esters of the central formula <IMAGE> (I) in which the radicals R1 are identical or different and are alkyl radicals having 1 to 8 carbon atoms, perfluoroalkyl radicals or dialkylaminoalkyl radicals, and R2 radicals are derived from an alcohol R2OH, n is a number from 1 to 6, and a is a number which on average is </=4, and a process of making the esters by transesterification. |
