Abstract

906,544. Polyepoxide-organo-polysiloxane reaction products. UNION CARBIDE CORPORATION. Oct. 20, 1958 [Oct. 21, 1957], No. 33348/58. Classes 2(5) and 2(7) The Specification discloses the reaction product of a polyepoxide with an organofunctional silicon compound of the formula where R and R<SP>1</SP> are hydrogen or a monovalent hydrocarbon radical, R<SP>11</SP> is a divalent hydrocarbon group, R<SP>111</SP> is a monovalent hydrocarbon group, n is an integer of at least 2, a is an integer of from 1 to 3, b is 0, 1 or 2 and the sum of a and b is not greater than 3, c is 0, 1 or 2, x and y are molecular fractions indicating the molecular proportions of their respective units in the compound and x+y is 1, Q is an alkyl or aryl radical or the radical where G is hydrogen or an alkyl or aryl radical and m is an integer of from 1 to 4 and X represents the radical or with a mixture of one or more such organofunctional silicon compounds, or with a mixture of one or more such organofunctional silicon compounds with an oxygen containing silicon compound of the general formula where Y is a hydroxy, hydroxy substituted hydrocarbon or 0¢. Many organofunctional silicon compounds are specified, examples being 3:5-diaminotriazinylaminopropyltriethoxysilane, 3 :S-dibutylaminotriazinylaminopropyl triethoxysilane, #-(m-aminophenyl) ethyl triethoxysilane, γ(3:5-dimethylaminophenyl)propylphenyldiethoxysilane and N-(yaminopropyl)-delta-aminobutyltriethoxysilane. The siloxanes derived from the organofunctional silicon compounds may be employed. Specified polyepoxides are butadiene dioxide, vinylcyclohexene dioxide, dicyclopentadiene dioxide, diglycidyl ether, the triglycidyl ether of glycerine, 3:4-epoxycyclohexylmethyl, 3:4-epoxycyclohexanecarboxylate, 1:6-hexanediol bis(3:4-epoxycyclohexane carboxylate), 1:1:1 -trimethylol propane tris(3:4-epoxycyclohexanecarboxylate), bis (3:4-epoxy-6-methylcyclohexylmethyl) maleate, bis(2:3-epoxycyclopentyl)ether, divinyl benzene dioxide and the di- and polyglycidyl ethers of 4:41-dihydroxydipheylpropane and 4:4<SP>1</SP>-dihydroxy-diphenyl methane. The examples describe the preparation of reaction products from the diglycidyl of bis-phenol-A and:-(1) a silicone oil containing gammacyanopropylmethyl silicone and delta-aminobutylmethylsilicone units; (2) #-m-aminophenylethylmethyl silicone cyclic trimer and tetramer; (3) a dimethyl silicone oil containing #-m-aminophenylethylmethyl silicone units; (4) a dimethyl silicone oil containing N,3:5-diaminotriazinyl-delta-aminobutyl-methyl silicone units; (5) N,γ-aminopropol-delta-aminobutyl methyl silicone cyclic trimer and tetramer; (6) m-aminophenylethyl methylsilicone oil and (7) γ-aminopropyltriethoxysilane. Specifications 795,894, 882,051, 882,053, 882,054, 882,062, 882,094, 882,095, 882,096, 882,097 and 882,103 are referred to.
