Abstract
The present invention relates to a composition comprising at least: (a) from 30% to 99.9% by weight of at least one recycled aliphatic polyamide, (b) from 0.1% to 10% by weight of at least one additive, (c) from 0% to 70% by weight of at least one virgin polyamide, (d) from 0% to 65% by weight of at least one filler, (e) from 0% to 15% by weight of at least one plasticizer, (f) from 0% to 30% by weight of at least one impact modifier. It also relates to the use of such a composition for the manufacture of objects, and to the corresponding objects.
Claims23
A composition comprising at least:
- (a) from 30% to 99.9% by weight of at least one recycled aliphatic polyamide having functions resulting from oxidation reactions chosen from primary amide functions, nitriles, chain-end methyl groups, alkenes, formamides, imides, carboxylic acids, alcohols and mixtures thereof in a mole ratio, relative to the secondary amide functions, which is greater than that of the same virgin aliphatic polyamide and/or of at least one recycled aliphatic polyamide having primary amine functions in a mole ratio, relative to the secondary amide functions, which is lower than that of the same virgin aliphatic polyamide,
- (b) from 0.1% to 10% by weight of at least one additive,
- (c) from 0% to 70% by weight of at least one virgin polyamide,
- (d) from 0% to 65% by weight of at least one filler,
- (e) from 0% to 15% by weight of at least one plasticizer,
- (f) from 0% to 30% by weight of at least one impact modifier.
