Organosilicon compounds of a novel class are disclosed including alpha , omega -bis(alkoxy silyl)-substituted alkane compounds represented by the general formula (RO)m(CH3)3-mSi-CH2)nSi(CH3)3-m(OR)m, in which R is a monovalent hydrocarbon group having 1 to 4 carbon atoms, e.g., methyl and ethyl, the subscript n is a positive integer in the range from 10 to 18 and the subscript m is 1, 2 or 3. The compound is useful as an additive in various kinds of synthetic resin-based compositions for the purpose of improving the properties such as flexibility, weatherability, cold resistance and mechanical strengths. |
