- R32, R33, R38, and R39 are alkyl or aryl groups;
- R34 and R37 are alkoxy groups;
- and R29 to R31, R35, R36, and R40 represent hydrogen or an alkyl group containing 2 to 10 carbon atoms.
A carbosilane of formula ##STR8## where R29 is hydrogen or an alkyl group containing 2 to 10 carbon atoms;
- R30, R31, R35, and R36 are hydrogen;
