Abstract: The additions of organosilicon compounds containing Si-H bonds to 2,2,3,3-tetrafluoropropyl allyl ether are studied. Aseries of unreported organosilicon com-pounds have been synthesized. The method of synthesis of 2, 2, 3, 3-tetrafluo-ropropyl allyl ether is improved. Some works on organosiliconpolymers containing fluorine are reported.
