- (a) 99.95-25% by weight of at least one polyamide-containing compound, said resin excluding modified polyolefins,
- (b) 0.05-5% by weight of at least one compound selected from the group consisting of acetate salts of magnesium, zinc and aluminum,
- which resin composition has an apparent melt viscosity according to ISO 11443 of less than 100 Pa.s, at a shear rate of 1000 s(-1) and at 0.1% by weight moisture content of the resin composition in the form of granules.
- 2. Composition according to claim 1 in which the polyamide-containing compounds comprise non-aromatic polyamides.
- 3. Composition according to claim 2 in which the non-aromatic polyamides are selected from the group consisting of the polyamides 4/6, 6, 6/6, 6/10, 6/12, 11 and 12.
- 4. Composition according to claim 3 which comprises polyamides 6 and 6/6.
- 5. Composition according to claim 1 in which the polyamide-containing compounds comprise at least one aromatic polyamide containing a metaxylylene diamide group, a terephthalic acid group or an isophthalic acid group.
- 6. Composition according to claim 1 wherein the compound selected from the group consisting of magnesium, zinc and aluminum salts is magnesium acetate or zinc acetate.
- 7. Composition according to claim 1 wherein (c) comprises 20-60% by weight of at least one reinforcing compound.
- 8. Composition according to claim 1 wherein (c) comprises 0.02-10% by weight of at least one additive compound of the group consisting of pigments, lubricants, plasticizers, stabilizers, flow aids, anti-oxidants, mold release agents, nucleating agents, impact modifiers and flame retardants.
- 9. Molded article comprising a thermoplastic resin composition according to and one of the preceding claims.
