Procedure

13.4 g of commercial 1,2,6-hexanetriol are added to 12.4 ml of diethoxymethane and the mixture is refluxed in the presence of 500 mg of toluenesulfonic acid acting as a transacetalisation catalyst. The ethanol is evaporated at 80° C. and the 4-(4-hydroxybutyl)-1,2-dioxolane obtained is purified by distillation. 7.3 g of this product and 4.6 g of epichlorhydrine are reacted in the presence of 2.8 g of potassium hydroxide (powder) and tetrabutylammonium chloride, to form the monomer 4-[(4-glycidyloxy)-butyl]-1,3-dioxolane
