    摘要: Organosilicon compounds, polymers and copolymers have been prepared containing acetylenic linkages between adjacent silicon atoms. The basic compounds are defined by the general formula R''(R2Si)m(C*C)- (C*C)-(SiR2)nR'''' where R'' and R'''' are each H, halogen, hydrocarbonoxy or -NQ2 as above defined, monovalent hydrocarbon or monovalent halogenohydrocarbon, m is 1 to 4, n is 0 to 4, R'''' being H, alkyl, aryl or trihydrocarbylsilyl when n is 0. The polymers can be defined by the unit formula (OSiR2-C*CC*C-SiR2-) and may be copolymers containing units of the formula QaSiO(4 a)/2 where Q is monovalent hydrocarbon or halogenohydrocarbon and a is 0 to 3. The novel compounds are useful as cross-linkers.

    摘要: 1,156,257. Organosilicon compounds. RHONE-POULENC S.A. 6 Sept., 1967 [8 Sept., 1966], No. 40798/67. Headings C3S and C3T. [Also in Division C5] Organosilicon compounds containing the radical where R 1 , R 11 and R 111 each represent hydrogen atoms or inert organic radicals and each R 1 is a saturated or aromatic hydrocarbon radical or an alkoxy, cycloalkoxy, aryloxy or aralkoxy group, may be hydrolysed or alcoholysed to form #-hydroxyalkyl silicon compounds. The compounds of Formula I are prepared by reacting a compound containing a silicon-hydrogen bond with a vinyloxysilane in the presence of a catalyst. The compound containing Si-H may be a mono- or poly-silane, polysilylalkane, polysiloxane or cyclopolysiloxane. Suitable catalysts are organic peroxides, ultra-violet light, nickel compounds and, preferably, platinum compounds. The #- siloxyalkyl silicon compound may be isolated or directly converted to the hydroxyalkyl compound. Where the original compound containing Si-H bonds also contain hydrolysable groups, the product will contain siloxane units. The hydrolysis may also take place in the presence of other hydrolysable silanes. The #-hydroxyalkyl compounds may be used as lubricants or in coating compositions or for the production of polycondensates by reaction with polyacids or polyisocyanates. The siloxyalkyl compounds of Formula 1 may also be used in impregnating compositions. Specification 1,060,910 is referred to.
