Versuchsvorschrift

In 100 ml of dry toluene containing 10 g of anhydrous sodium carbonate was dissolved 20 g of monomethoxypolyethylene glycol having an average molecular, weight of 4000 (Nippon Oil and Fats) and the solution was heated at 110° C. for 30 minutes. Then, 500 mg of cyanuric chloride was added and the mixture was heated at 110° C. for 24 hours. The reaction residue was filtered off, followed by addition of 300 ml of petroleum ether to cause precipitation. The precipitate was washed with several portions of petroleum ether to recover 10 g of 2,4-bis(O-methoxypolyethylene glycol)-6-chloro-s-triazine (yield 50%).
