Versuchsvorschrift

A sample vial was filled with 2 g of isopropoxy benzoyl chloride and SnCl4 was injected. The mixture was homogenized and then kept at the reaction temperature chosen. After the reaction 50 mg of the solidified red-brown reaction mixture was hydrolyzed in 1 ml of a mixture of CD3OD/D2O/NaOD (12:3:1, weight ratios) (2 hours, 60° C.) and the degree of polymerization (dp) was determined by NMR end-group analysis.
