Mixtures of a polyhydrocarbon and an incompatible polymer in the form of a dispersion in which the polymer of the disperse phase has an average particle size not exceeding 25 microns, are prepared by mixing the polymers in the presence of a polymeric dispersing agent having a molecular weight of at least 1000 and which is at least partially compatible with the polyhydrocarbon and the incompatible polymer. Specified polyhydrocarbons are polyethylene and polypropylene. Specified incompatible polymers are polyhexamethylene adipamide, poly epsilon caprolactam, poly omega amino undecanoic acid, polyethylene terephthalate, polycarbonates, polyurethanes and polyureas. Specified dispersing agents are polyamides and copolyamides, e.g. poly omega amino undecanoic acid, copolyamides derived from a lactam and substituted or unsubstituted omega amino undecanoic acids, from substituted or unsubstituted diamines and dibasic carboxylic acids and salts of dicarboxylic acids and diamines, e.g. hexamethylene diammonium adipate. The compositions may be made into films and filaments. Examples describe the preparation of dispersing agents by reacting (1) dilinoleic acid, hexamethylene diamine and hexamethylene diammonium adipate in phenol or solvent, (2) 11-N-(2-tridecyl) amino undecanoic acid and epsilon caprolactam in the presence of omega amino undecanoic acid as catalyst, (5) 11-N-hexadecyl amino undecanoic acid and epsilon caprolactam in the presence of omega amino undecanoic acid as catalyst, (6 and 7) dilinoleic acid, hexamethylene diamine and epsilon caprolactam, and (8 to 10) N-C14- 18 alkyl propylenediamine/sebacic acid salt and epsilon caprolactam. Mixtures of polyhexamethylene adipamide and (1 to 10) polyethylene and (11) polypropylene using the above identified dispersing agents and (3) polyamino undecanoic acid and (4) polyhexamethylene sebacamide.ALSO:Hexadecylamino undecanoic acid is prepared by adding 11-bromoundecanoic acid to a solution of cetyl amine in methylated spirits and refluxing on a water bath.
