摘要:
A solid material is subjected to surface treatment by chemically bonding onto a surface of the solid material a stabilized monofunctional silanol represented by R1R2R3SiOH. R1, R2 and R3 may be the same or different, and each represent a substituent group independently selected from a substituted or unsubstituted, monovalent hydrocarbon group having from 1 to 40 carbon atoms or a substituted or unsubstituted, monovalent heterocyclic group having from 1 to 100 carbon atoms. The monofunctional silanol has a dehydrative self-condensation rate lower than triethylsilanol.

An organosilicon compound having an amino group is provided. This compound is represented by the following general formula (1): wherein R1 and R2 respectively represent an unsubstituted or substituted aliphatic monovalent hydrocarbon group containing 1 to 10 carbon atoms with the proviso that the R1 and R2 may together form a ring with the nitrogen atom to which they are bonded, and that R1 and R2 may contain a heteroatom; R3 and R4 independently represent an unsubstituted or substituted monovalent hydrocarbon group containing 1 to 10 carbon atoms; and n represents an integer of 0 to 2. Use of this compound enables production of a polymer product having excellent mechanical properties, high heat resistance, and high transparency. The solution of this compound is stable, and can be stored for a long time, and when used for a polymer modifying agent, it facilitates introduction of amino group and hydroxy group.

Bissilylamino group-bearing chlorosilane compounds of formula (1): [(CH3)3Si]2NCH2CH2CH2Si(CH3)nCl3−n (1) wherein n is 0 or 1 are novel. They are useful as silane coupling agents and surface treating agents. They can be readily converted, through reaction with alcohols, to bissilyl group-bearing alkoxysilane compounds which are useful as intermediates for the synthesis of aminopropyl-modified silicone oil. The invention also provides an industrially advantageous method capable of preparing the bissilylamino group-bearing chlorosilane compounds.

摘要:
A halopropyldimethylchlorosilane is prepared by reacting dimethylchlorosilane with an allyl halide in the presence of an iridium catalyst. The reaction is effected in the presence of an internal olefin compound, typically 1,5-cyclooctadiene. The internal olefin compound suppresses deactivation of the iridium catalyst during reaction. Using a smaller amount of the iridium catalyst, the process produces the halopropyldimethylchlorosilane in high yields.
