Document Type and Number:
Japanese Patent JP2821494
Kind Code:
B2
Abstract:
The specification describes and claims certain organosilicon compounds and the preparation thereof. The organosilicon compounds comprise (A) a silane according to the general formula R<1>aAbSi(R sec NXR min )c or (B) a polysiloxane comprising one or more siloxane units according to the general formula any remaining units of the polysiloxane being at least predominantly according to the general formula A represents a hydroxyl or a hydrolysable group, R<1> represents a monovalent hydrocarbon group having up to 8 carbon atoms, R<2> represents a hydroxyl group, a group R<1>, a group OR<1> or a group COR<1>, R<4> represents a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, an alkenyl group or an aryl group, R min represents a group R<4> or a group X, R sec represents a divalent hydrocarbon group which may have nitrogen, oxygen or sulphur present in the carbon chain, X represents a group CO(CHR)nOH in which R represents a hydrogen atom or an alkyl group, a has the value 0, 1, or 2, b has the value 1, 2, or 3, c has the value 1 or 2, the sum of a + b + c = 4, m has the value 0, 1 or 2, p has the value 1 or 2 , q has the value 0, 1, 2 or 3, r has the value 0, 1 or 2, and n has a value in the range 2 to 7. The organosilicon compounds are useful in compositions for treating fabrics. Preferred organopolysiloxanes are of the average general formula wherein not less than 80% of the groups R<2> are methyl groups, x has an average value from 20 to 1500, y has an average value from 0 to 50 and z has an average value from 0.5 to 50. In preferred materials the ratio of y : z lies in the range 1 : 4 to 4 : 1 and the ratio z : x is less than 5 : 100.
