Hydrophilic oxygen permeable polymers

A composition formed by polymerizing the mixture:

• (a) 1 to 98 weight percent siloxane monomer represented by the formula ##STR6## where A denotes an acrylate or methacrylate radical, R.sup.5 and R.sup.6 independently denote alkyl radicals with one to six carbon atoms or phenyl radicals, x and y are on the average one to six, and mix at least one;
• (b) 1 to 50 weight percent of an internal wetting agent represented by the general formula ##STR7## where R.sup.1 and R.sup.2 independently denote a hydrogen atom or a lower alkyl radical with one to six carbon atoms, and R.sup.3 and R.sup.4 independently denote alkyl radicals with one to six carbon atoms or a cyclohexyl radical.
