This invention relates to amines which are suitable for making silicone containing polymer materials employed as wire coatings or as passivation and/or protective coatings for semiconductor devices.
2. Description of the Prior Art
The electrical industry is always seeking suitable coating materials which will improve the physical and/or electrical properties of electrical articles to which it is applied. The material must be one that is easily applied and cured in place. The material when cured must also be easily repairable when required and only a small amount of material be applied to the article to achieve the desirable electrical and chemical properties. Suitable coating materials may include a copolymer which when cured can be the reaction product of a silicon-free organic diamine, an organic tetracarboxylic dianhydride and a polysiloxane diamine. Any improvements in electrical and physical properties of coating materials which can be achieved by improving the process of making one or more of the ingredients is most desireable by industry.
Therefore, it is an object of this invention to provide a new and improved polysiloxane diamine suitable for use in making wire coatings and junction and/or protective coating materials for semiconductor devices.
Another object of this invention is to provide a new and improved silicone containing bis-thioether aromatic amine which enhances the antioxidant properties and thermal stability of coating materials made therefrom.
A further object of this invention is to provide a new and improved process for making the silicone containing bis-thioether aromatic amine.
Other objects of this invention will, in part, be obvious and will, in part, appear hereinafter.
In accordance with the teachings of this invention there is provided a new and improved amine for making polymer materials with improved antioxidant and thermal stability properties and a process for making the amine. The new amine is a silicone containing bis-thioether aromatic amine having the general formula ##STR1## wherein Q is an aromatic nucleus

The new amine is suitable for making polymers with improved physical properties for electrical wires and protective and/or junction coatings for semiconductor materials.
A preferred form of the new amine embodies sulfone for Z in the formula and imparts excellent thermal stability to polymers made from the amine.
I have discovered a silicone containing bis-thioether amine which is easy to formulate and which can improve the anti-oxidant and thermal stability properties of coating materials made therefrom. The new amine has the general formula: ##STR2## wherein Q is an aromatic nucleus

R3 is a .Iadd.hydrogen atom, a .Iaddend.hydrocarbon radical or a functional group such as a halogen, and
x is 0 or greater.
A preferred form of the new amine of Formula (I) has sulfone as part of the general formula in order to produce polymer films which have high thermal stability as well as excellent anti-oxidant properties.
The preferred form of the new amine of Formula (I) may be made by charging a 3-necked flask with 43.28 parts of 50% aqueous sodium hydroxide solution, 112 parts dimethylsulfoxide (DMSO), 120 parts toluene and 68.75 parts p-amino-thiophenol. The reaction is brought to reflux in a nitrogen atmosphere with rapid agitation. The water of the charged ingredients (the aqueous hydroxide solution) and the water formed during the neutralization reaction is removed azeotropically and collected in a Dean Stork trap. The refluxing solvent is returned to the reaction mixture. The pot temperature, that is the temperature of the reaction mixture, climbs from an initial 110° C. to about 180° C. during a period of from 7 to 8 hours of stirring. At the end of this time period water is no longer evolved from the reaction mixture.
The reaction mixture is then cooled to about 80° C. At this temperature of about 80° C., 86.6 parts of bis(chlorobutyl)tetramethyldisiloxane is added dropwise to the reaction mixture. The chemical reaction which occurs during the dropwise addition is slightly exothermic. Therefore the addition is controlled to retain the reaction temperature at about 80° C. Upon completion of the silane addition, the reaction is allowed to proceed at about 80° C. for a period of time which is usually overnight.
The reaction is monitored such, for example, as by use of a GC analytical means. When GC analysis indicates a new peak having a long retention time, the reaction is complete.
The reaction mixture is filtered and the solvents, toluene and DMSO, are removed under a reduced pressure of about 10 mm. The stripped mixture is distilled and the desired end product is recovered at a temperature of from about 310° C. to 315° C. at from 0.1 mm to 0.5 mm pressure. The chemical structure may be confirmed by suitable chemical analysis means such as IR on NMR. The structure of the recovered new amine of Formula (I) has the chemical name bis-(p-aminophenylthiobutyl)tetramethyldisiloxane. A yield of about 75 percent is achieved by this process.
The new amines of this invention [Formula (I)] are suitable for making a copolymer material which is the product of the condensation reaction of an organic diamine with one of the new amines with molar amounts of an organic dianhydride and having a general formula which is one selected from the group consisting of ##STR3## with from 0 to 99 mol percent intercondensed structure units of the formula: ##STR4## wherein A is one of the new silicone containing bis-thioether aromatic amine of Formula (I)
R2 is a tetravalent organic radical or an alkylene and/or an arylene dioxy-Bis (phenyline) radical defined by the following general formula: ##STR5## m and n are the same or different integers greater than 1 and preferably from 10 to 10,000 or more;
Y is a divalent silicon-free organic radical which is the residue of an organic diamine or a macrocyclic crown ether;
x is 0 or greater, and
R4 is a member selected from the group consisting of (1) a divalent organic radical and (2) divalent organic radicals of the general formula: ##STR6## wherein D is a member selected from the group consisting of divalent radicals of the formulas: ##STR7## p is 0 or 1, y is a whole number from 0 to 5, and the divalent bonds of the --O--R4 --O-- radical are equally situated on the phthalic anhydride end group, for example, in the 3,3'-positions or the 4,4'-positions.
The divalent organic radicals of (1) for R4 of Equation V may be any of the following: ##STR8##
The above-mentioned block and random copolymer materials can be prepared by effecting reaction, in the proper molar proportions, of a mixture of ingredients comprising a silicone Bis-(ether aromatic amine), the structure of which is found in Formula I and a silicone-free diamino compound of the formula:
NH.sub.2 --Y--NH.sub.2 (VIII)
with molar amounts of dianhydride of the formula: ##STR9## wherein R4 and Y have the meaning as given before.
Other organic tetracarboxylic dianhydrides containing no ether linkages can be added in an amount up to about 50%, by molar requirements, of the total anhydride requirements of the reaction system with the diamino functional compounds. For example, the mixture of ingredients may include a second tetracarboxylic dianhydride having the formula ##STR10## wherein R2 has the meaning previously recited herein. Films resulting from the incorporation of the optional addition of a second ether-free dianhydride are more solvent resistant and more stable to attack by alkali, amines or hydrazine reagents. Thus the reaction product may additionally contain up to 50 mol percent of recurring structural units of the formula: ##STR11## with 1 to 99 mol percent intercondensed structural units of the formula: ##STR12## wherein R, R', R2 and Y have the meaning as given before, and

The following is an example of the use of one of the new silicone containing bis-thioether aromatic amines in making a polymer material:
To a reaction mixture consisting of 58.44 g 1,3-bis-(p-aminophenylthiobutyl)tetramethyldisiloxane and 29.94 g m-phenylenediamine in 636 g dry N-methyl-pyrrolidone and cooled to 0° C. was added portionwise, over a four hour period, 127.50 g benzophenonetetracarboxylic dianhydride. The solution became dark amber and its viscosity greatly increased toward the latter half of the reaction.
Upon complete anhydride addition, solution was not complete but stirring was maintained for 10 additional hours at ambient temperature. At this time, a dark amber clear viscous solution resulted which wet the sides of the flask well. The product obtained was a silicone polyamic acid precursor solution containing 30 mol percent of 1,3-bis-(p-aminophenylthiobutyl)tetramethyldisiloxane.
A sample of the above reaction product material in the form of a precursor solution was disposed on the surface of a glass slide to form a coating 0.2 mil in thickness. The coated slide was then placed in a furnace to effect a curing of the applied precursor solution material in the following manner:
2 hours at 135° C.±10° C.
2 hours at 185° C.±10° C.
2 hours at 250° C.±10° C.
1/2 hour at 300° C.±10° C.
After curing and upon removal of the control slide from the furnace, examination of the resulting film was performed. The cured film bonded very tenaciously to the glass slide. The coating still bonded tenaciously to the glass slide even after immersion in boiling water for a period of 6 hours. The cured coating material also had excellent anti-oxidant properties and exhibited good thermal stability up to the order of 450° C.
Cured films as obtained above have been found suitable for use as electrical wire coatings for motor and generator windings as well as for protective and/or junction coatings for semiconductor devices.
