Abstract:
R1-C(-R2)(-R3)-O-CH2-COO-R4-SI(-R5)(-R6)-R7
1. BODIES OF SILICA GEL GRAFTED WITH ORGANIC GROUPS TO MODIFY THE SURFACE PROPERTIES THEREOF IN WHICH THE GRAFTED GROUP ORIGINATES FROM AN ORGANO SILANE SELECTED FROM THE GROUP CONSISTING OF AN ORGANO SILANE HAVING THE FORMULA
WHEREIN R1, R2 AND R3 ARE MONOVALENT GROUPS SELECTED FROM THE GROUP CONSISTING OF CX3 AND X WHEREIN X IS HALOGEN AND AT LEAST ONE X IS FLUORINE, R4 IS ALKYLENE, AND R5, R6 AND R7 ARE GROUPS ATTACHED DIRECTLY TO THE SILICON ATOM, AND ARE SELECTED FROM THE GROUP CONSISTING OF HALOGEN AND ALKYL, WITH AT LEAST ONE OF THE R5, R6 AND R7 GROUPS BEING HALOGEN; AND A COPOLYMER OF A VINYL TRIALKOXY SILANE AND A COMPOUND OF THE FORMULA
CH2=CH-COO-C(-F)(-CF3)2
