Abstract

Siloxane polymers and copolymers containing certain silicon-bonded aryl-containing organic radicals (see Division C3), are used per se or in admixture with (as antioxidant additives) siloxane oils or blends of such oils, as lubricants or hydraulic fluids, e.g. as a fluid clutch in a torque converter. The blends are usually alkoxy- or hydroxy-terminated diorganopolysiloxanes containing 9 to 25% (by wt. of the blend) of a cyclic diorganosiloxane depolymerizate (i.e. a mixture of lower cyclics in which the tetramer is predominant). Examples disclose (VI) various mixtures of dimethylsiloxane oils with the novel antioxidants and comparative mixtures of the same oils with known antioxidants; and (VII, VIII) mixtures of siloxane oil blends with the novel antioxidants and comparative mixtures of the same blends with known antioxidants.ALSO:An organosilicon polymer having the formula <FORM:1064021/C3/1> wherein R is a monovalent hydrocarbon radical with or without substituents, R2 is a divalent substituted aryl-containing organic radical, W is an -OR1, -SR1, -NRR1 or -OOCR1 radical, R1 is a monovalent substituted aryl-containing organic radical, A is an -Ac, -SiR3, -SiRW2, -SiW3 or -R1 radical, A is an acyl radical, B is an AcO-, R3SiO-, W2RSiO-, W3SiO- or W- radical, m has a value of at least 0, n has a value of at least 1, p has a value of at least 0, and wherein the polymer must contain at least 1 R1 or R2 radical, or a copolymer thereof with conventional siloxane units, can be made by reacting (1) a compound of formula R3SiO(R2SiO)nAc or AcO(R2SiO)nAc with (2) a substituted phenol of the formula R1OH or R1OM, wherein M is a metal, e.g. Na, K or Ca. The reaction can be effected at 0 DEG to 250 DEG C., a base, e.g. pyridine, being necessary to promote the reaction at lower temperatures. Several alternative methods of preparation are mentioned, and numerous examples of reactants are given. In a typical Example (3), p-HO.C6H4.NH.C6H5 was reacted with AcO(Me2SiO)7.45Ac at 120-131 DEG C. to yield a dark coloured liquid of the formula <FORM:1064021/C3/2> The polymers can be copolymerized with conventional siloxanes. Uses.-The polymers and copolymers can be used in known manner to form oils, which can be used as lubricants and hydraulic fluids, and gums, which can be mixed with known fillers and organic peroxides and cured to elastomers, or they can be added, as antioxidants, to siloxane elastomers and siloxane oils or blends of such oils; the blends are usually alkoxy- or hydroxy-terminated diorgano-polysiloxanes containing 9 to 25% (by wt. of the blend) of a cyclic diorganosiloxane depolymerizate (i.e. a mixture of lower cyclics in which the tetramer is predominant). Examples disclose (VI) various mixtures of dimethylsiloxane oils with the novel antioxidants and comparative mixtures of the same oils with known antioxidants; and (VII, VIII) mixtures of siloxane oil blends with the novel antioxidants and comparative mixtures of the same blends with known antioxidants.
