Abstract: An antifriction high temperature composite is formed of a metal or other support or substrate and a cast thin lubricating film. The thin film has a plastic matrix containing a multiplicity of dispersed small discrete solid lubricant filler particles. The plastic is either an aromatic polyamide-imide or an aromatic polyimide and the filler is a finely divided solid lubricant such as MoS2.

Abstract: WHERE N IS AN INTEGER GREATER THAN 10 AND PREFERABLY GREATER THAN 20. A novel amine having the general structural formula:
WHEREIN: A is selected from the group consisting of
Amide-imide polymers formable in deep section and prepared by the condensation reaction of at least one of a diacid halide or a polyanhydride or equivalent, and a diamine containing at least one imide linkage. Soluble amide-imide polymers having the general formula:
D R A W I N G
R is a trivalent organic radical in which the two valences included in the imide ring are attached to adjacent carbon atoms and the third valence is attached to a different carbon atom, R'' is a divalent organic radical, R'''' is a tetravalent organic radical in which the bonds are attached to two pairs of adjacent carbon atoms, so that five or six membered imide rings are formed, A, B, C, AND D ARE INTEGERS FROM 0 TO 6, THE SUM OF A, B, C, AND D IS AN INTEGER FROM 1 TO 6, AT LEAST ONE R or R'''' group is included in the molecule, and the bracketed groups are in any order. Although one or more of the R, R'', or R'''' radicals may contain one or more additional amino groups or other compatible linkages, preferably said amine contains only said terminal amino groups.
