    • The invention relates to a copolymer, which includes 20 to 95 percent by weight, based on the total weight of the copolymer, of structural units derived from at least one hydrophilic monomer, and 5 to 80 percent by weight, based on the total weight of the copolymer, of structural units derived from at least one monomer according to the general formula I wherein R1, R2 and R3 each independently of each other denote hydrogen or alkyl-, Y: denotes O or NR4 with R4 selected from hydrogen or alkyl-, X: denotes O, S, SO or SO2, S denotes a structural unit selected from CHR5 or (CHR5CHR5O)iCH2, wherein all of the R5 each independently of each other denote hydrogen or alkyl-, n and i independently of each other denote an integer between 1 and 10 and m denotes an integer between 2 and 6, and wherein the copolymer has a water content from 1 to 59 percent by weight based on the total weight of the copolymer. Furthermore, the invention relates to an ophthalmologic composition.
