Abstract

The organosilane compound of the invention is represented by the general formula EQU CIFC.dbd.CF--O--(R.sup.1 --O--).sub.m --(--R.sup.2 --).sub.n --CHR.sup.3 --CH.sub.2 --SiR.sub.3, in which, for example, each R.sup.1 is an ethylene group, R.sup.2 is a methylene group, R.sup.3 is a hydrogen atom, each R is an alkyl or alkoxy group, the subscript m is zero, 1, 2 or 3 and the subscript n is zero or 1. The terminal group of CIFC.dbd.CF--O-- has copolymerizability with conventional fluorine-containing polymerizable unsaturated compounds, e.g., tetrafluoroethylene, so that it is useful as a modifying agent of fluorine-containing polymers. A synthetic method for the compound is disclosed.
