Abstract
A fluorinated organic silicon compound of a structure having a fluorinated polyether group in its backbone and an isopropenoxysilyl group attached at either end forms a compliant coating on the surface of any substrate such as silicone rubber which is effective in imparting water and oil repellency and stain resistance to silicone rubber surface.
Claims2
A fluorinated organic silicon compound of the following general formula (1):
- ##STR11## wherein a and b each are an integer of 0 to 30, n is an integer of 0 to 10, with the proviso that n is an integer of 1 to 10 when both or either one of a and b is 0, and c is equal to 2 or 3.
A method for preparing a fluorinated organic silicon compound of the following general formula (1):
- ##STR12## ##STR13## wherein a and b each are an integer of 0 to 30, n is an integer of 0 to 10, with proviso that n is an integer of 1 to 10 when both or either one of a and b is 0, and c is equal to 2 or 3,
- said method comprising the step of reacting a compound of the following general formula (4):
- ##STR14## wherein a, b and n are as defined above with diisopropenoxymethylsilane or triisopropenoxysilane.
