In order that those skilled in the art will be better able to practice the invention, the following example is given by way of illustration and not by way of limitation. All parts are by weight.
Example
There was added 10 drops of a 5% platinum catalyst prepared in accordance with Karstedt, U.S. 3 ,775 ,442 , assigned to the same assignee as the present invention, to a mixture while it was being stirred of 69.4 g (0.42 mole) of 5-norbornene-2 ,3-dicarboxylic acid anhydride, 26.8 g (0.2 mole) 1,1 ,3 ,3-tetramethyIdisiloxane and 100 ml of dry chlorobenzene. The resulting mixture was heated with stirring to 70-80°C for 4 hours and then 100-110°C overnight. After cooling, carbon black was added and the solution was stirred for 30 minutes at room temperature. Filtration, removal of the solvent at 100°C with a vacuum pump and addition of dry diethylether resulted in the precipitation of a white
crystalline solid. Based on method of preparation, the product was 5,5'-(1,1,3,3-tetramethyl-1,3- disiloxanediyl)-bis-norbornane-2,3-dicarboxylic anhydride having the formula,
A series of silicon-imide copolymers including block copolymers were prepared from various mixtures of the above 5,5'-(1,1,2,3-tetramethyl-1,3-disiloxanedyl)-bis-norbornane-2,3-dicarboxylic dianhydride, hereinafter referred to as (NSDA), and benzophenone tetracarboxylic dianhydride (BPDA).
There was added to a solution of 0.991 grams
(5 x 10-3 moles) of methylene dianiline and 5 ml of dimethylformamide while it was stirred under nitrogen, a mixture of 0.457 grams (10-3 mole) of NSDA, 1.289 grams
(4 x 10-3 mole) of BPDA and 5 ml of dimethylformamide. The resulting solution was stirred for 2 hours at room temperature. There was obtained a silicone-amide acid copolymer. The solution was then poured into a glass dish and dried at 80°C for 1 hour, and 150°C for 2 hours in an oven cast under flowing nitrogen. Based on method
of preparation , IR and NMR analysis , there was obtained a silicone-poly copolymer consisting essentially of norbor nane terminated dimethyls iloxane groups of the formula ,
chemically combined with imide groups having the formula ,
The same procedure was repeated to prepare an additional silicone-imide block polymers within the scope of formula (1) as shown by the following formula:
Glass transition temperatures (Tg) of the copolymers were measured by differential scanning calorimetry (DSC) and are shown in the following table, where b, c and d values in the above formula are shown. Thermal oxidative stabilities of the copolymers were measured by thermogravimetric analysis (TGA). Ten percent weight loss temperatures of the copolymers under N2 and air are
also shown:

The above results show that the silicone-imide copolymers of the present invention can be used as high temperature insulation for metallic conductors which possesses superior oxidative stability. For example, a copper wire is dipped into a dimethylformamide solution of the silicone-amic acid copolymer and removed from the solution and allowed to air dry. The coated wire is then heated to 200°C to convert the amide acid coating on the wire to the imide state. The resulting silicone-imide copolymer coating is superior high temperature insulation possessing superior oxidative stability.
Although the above example is directed to only a few of the very many variables of the silicone-imide copolymers of the present invention, it should be understood that the present invention is directed to a much
broader variety of such silicone-imide copolymers including block copolymers , based on the employment of norbornane anhydride-terminated polydiorganosiloxane of formula (1) with organic diamine of formula (2) and optionally with mixtures of norbomane anhydride-terminated polydiorganosiloxane of formula (1) and other organic dianhydrides of formula (3 ) as previously taught in the description preceding these examples.
