摘要
A water-insoluble copolymer which is composed of (a) from 39.9 to 60% by weight of N,N-dimethylacrylamide or N,N-dimethylmethacrylamide; (b) from 60 to 39.9% by weight of N-alkylated acryl amides or N-alkylated methacryl amides; (c) from 0.1 to 0.7% by weight of a proton-sensitive fluorophore which is covalently bonded to the copolymer; and (d) from 0 to 20% by weight of a diolefinic crosslinking component. The copolymer is used in the form of a membrane on a transparent support material as an optical sensor for ionic strength-independent pH value determination.
