20.0 g of poly(HEMA4.0 -MMA1) was dissolved in 500 cc THF plus acetone (3:2) at boiling (60° C.). 0.271 g CMU was added and stirred until dissolved. 0.245 g dicyclohexylcarbodiimide and 25 mg dimethylaminopyridine, each dissolved in THF, were added and the solution stirred for 3 hours at boiling (60° C.). The reaction solution was then work-up as described for i., giving a limegreen powder, weight 13.81 g (69% yield) of poly(HEMA4.0 -MMA1) with a theoretical molar substitution of 0.96% umbelliferone on HEMA monomer. Actual substitution was 0.53%.
