Abstract

PURPOSE: To obtain the titled substance with its terminal groups blocked with trimethylsilyl groups in high purity, in high yield, and at low cost, by subjecting a trimethylsilanol- or OH-containing organopolysiloxane and a Cl-containing organic silicon compound to a reaction through removal of hydrochloric acid.
CONSTITUTION: A compound shown by the formula I (R is hydrocarbon group; l is positive integer ≤4) synthesized from trimethylsilanol or trimethylsilanol and organodichlorosilane as starting mterials and a compound shown by the formula II (where c is 1, a=b=3, m=1W4; when c is 2, a=b=1, m=0) are subjected to a reaction through removal of hydrochloric acid, to give a compound shown by the formula III (n is positive integer of 1W9). The reaction is carried out at -50W 120°C, a trapping agent (e.g., triethylamine) for hydrochloric acid, organic solvent, etc. may be used.
USE: Lubricant, antifoaming agent, parting agent, additive for coating compound, and polish.
