Abstract

A vulcanizable composition is prepared by mixing a convertible organopolysiloxane and finely divided reinforcing silica which is surface modified before or during mixing with a disilazane and/or silylamine. The organopolysiloxane is preferably a linear polymer having unit formula <FORM:1024234/C3/1> where n is on average 1.95-2.05 and R may be alkyl, e.g. methyl, ethyl, propyl; alkenyl, e.g. vinyl, alkyl; aryl, e.g. phenyl, naphthyl; or substitutes hydrocarbon, e.g. chlorophenyl, trifluoropropyl, or cyanopropyl radicals. The disilazanes <FORM:1024234/C3/2> have organic radicals attached to Si, and organic radicals or H atoms attached to N, e.g. hexamethyl, divinyltetramethyl and diphenyltetramethyl disilazane. Silylamines are R31SiNR211, where R1 is H atom, or hydrocarbon or substituted hydrocarbon radical and R11 is H atom or hydrocarbon radical, e.g. Ph3SiNH2, Ph2MeSiNH2, Et3SiNMe2\t and Me3 SiNHEt. The N-Si compound may be added to the silica as a liquid, or employed in a mutual solvent, and the treated silica is then added to the organopolysiloxane; or the silica, organopolysiloxane, and N-Si compound may be cold mixed together; in either case the proportions used are 15-150:100: 5-50 respectively. The mixture is heated during or after mixing to not above 300 DEG C., with reflux if necessary, and is subsequently vulcanized, e.g. with organic peroxides, or high energy radiation, or by adding an alkyl silicate or polysilicate and a siloxane condensation catalyst. Other fillers, e.g. TiO2, MgO, or diatomaceous earth, may also be incorporated.ALSO:Finely divided reinforcing silica is surface modified by treating with a disilazane and/or silylamine. The disilazanes, <FORM:1024234/C1/1> have organic radicals attached to Si, and organic radicals or H atoms attached to N, e.g. hexamethyl, divinyltetramethyl and diphenyltetramethyl disilazane. Silylamines are R31SiNR112, where R1 is H atom, a hydrocarbon or substituted hydrocarbon radical, and R11 is H atom or hydrocarbon radical, e.g. Ph3SiNH2, Ph2MeSiNH2, Et3SiNMe2 and Me3SiNHEt. The N-Si compound may be added to precipitates or fume silica as a liquid or employed in a mutual organic solvent, and the treated silica is incorporated into a convertible organopolysiloxane; or the silica may be treated in situ by mixing it with the organopolysiloxane and N-Si compound; in either case the proportions used are 15-150 : 100 : 5-50 respectively. The mixture is heated during or after mixing to not above 300 DEG C., with reflux if necessary, and is subsequently conventionally vulcanized.
