Free-flowing polyamide molding compounds and blends

Free-flowing polyamide molding compounds and blends which comprise a mixture of

• i) 85 to 99.9% by weight polyamides,
• ii) 0.1 to 15% by weight, based on the total weight of i) and ii), of special low molecular weight, liquidcrystalline esters and/or ester amides corresponding to formula (II) with statistical distribution of the structural units ##STR81## in which R.sup.3 is alkyl or an optionally substituted aryl;
• Ar.sup.a is a difunctional, optionally substituted mononuclear or polynuclear aromatic radical containing 6 to 24 carbon atoms;
• Ar.sup.b is a difunctional, optionally substituted, mononuclear or polynuclear aromatic radical containing 6 to 30 atoms;
• R.sup.4 and R.sup.5 represent an optionally substituted, difunctional mononuclear or polynuclear aromatic radical containing 6 to 24 carbon atoms;
• Y' represents --O--, ##STR82## and wherein Y' is bonded to a terminal group ##STR83## represents the --O-- or --NH--;
• b is 0to 10;
• C is 1 to 9;
• d is 0 to 9;
• e is 0 to 3
• and wherein the terminal groups are formed by structural elements ##STR84## and wherein the average molecular weight Mn of the compounds corresponding to formula (II) is no greater than 4,000 with the proviso that (II) containing 7-25 aromatic partial structures, and iii) from 0.001 to 150% by weight, based on the total weight of components i) and ii), of additives comprising glass fibers, aramide-fibers, carbon fibers, plasticizers, antioxydants, pigments, dyes, weathering stabilizers, lubricants, flow aids, mold release agents, additives which reduce water absorption, flame proofing agents or polymeric blending components.
