Abstract N,N'-bis(3,4-dicyanophenyl) alkanediamides of the general formula: ##SPC1## Wherein R = (CH 2 ) n -2 and (CH 2 ) x CH(CH 3 )(CH.sub. 2) y ; n = 3 to 20; x = 1 to 8; and y = 1 to 8, prepared by reacting 4-aminophthalonitrile with a saturated aliphatic dicarboxylic acid halide. These dinitriles readily polymerize through heating by themselves or with a metal or with a salt to form polyphthalocyanine resins, of the infinite molecular weight type which are useful as coatings, laminates, adhesives, filament windings, and castings. The general formulas for these polyphthalocyanine resins are: ##SPC2## ##SPC3## Wherein R = (CH 2 ) n -2 and (CH 2 ) x CH(CH 3 )(CH 2 ) y ; n = 3 to 20; x = 1 to 8; and y = 1 to 8.
A polyphthalocyanine resin having the general formula: ##SPC11## wherein R = (CH 2 ) n -2 , (CH 2 ) x CH(CH 3 ) (CH 2 ) y ; n = 3 to 20; x = 1 to 8; and y = 1 to 8.
