Abstract: 1,167,527. Polyamide-phenoplast compositions. BADISCHE ANILIN- & SODAFABRIK A.G. 11 Nov., 1966 [13 Nov., 1965], No. 50624/66. Heading C3R. [Also in Division H1] A binder for securing ferromagnetic particles to a substrate (see Division H1) comprises a mixture of (I) 60 to 99% by weight of a copolyamide of (a) 20 to 60% by weight of at least one lactam having more than six ring members and (b) 80 to 40% by weight of a mixture of at least one dicarboxylic acid having 6 to 20 carbon atoms, the latter mixture having at least one aliphatic dicarboxylic acid or diamine of 6 to 20 carbon atoms and represented by the formula in which Z denotes -CH 2 NH 2 or -COOH, R is an alkyl radical having at least 2 carbon atoms, R 2 is hydrogen or an alkyl radical having at least 2 carbon atoms and x and y each denote an integer from 1 to 5, and/or p,p 1 - diamino dicyclohexyl methane, the copolyamide being soluble in an organic solvent, and ((II) 40 to 1% by weight of a reaction product of formaldehyde and an aromatic compound having a phenolic hydroxy group and suitable for the formation of a phenolic resin. Numerous suitable lactams or corresponding amino acids are mentioned. Lists are given of compounds of the above general formula and of other C 6-20 dicarboxylic acids and diamines which may contain aliphatic or aromatic ring systems. The phenoplasts may be derived from phenol, cresols or naphthols and may be modified by conventional additives; in examples, the phenoplast comprises a polyester of 1 mole of trimethylol propane and 0.8 mole of adipic acid as modifier. Various solvents and optional additives are mentioned.
