Patent ID: 7008629

Claim:
A composition comprising: (i) at least one heteropolymer chosen from polyamide polymers of formula (I): in which: n is an integer which represents the number of amide units such that the number of ester groups present in said at least one polyamide polymer ranges from 10% to 50% of the total number of all ester groups and all amide groups comprised in said at least one polyamide polymer; R 1 , which are identical or different, are each chosen from alkyl groups comprising at least 4 carbon atoms and alkenyl groups comprising at least 4 carbon atoms; R 2 , which are identical or different, are each chosen from C 4 to C 42 hydrocarbon-based groups with the proviso that at least 50% of all R 2 are chosen from C 30 to C 42 hydrocarbon-based groups; R 3 , which are identical or different, are each chosen from organic groups comprising atoms chosen from carbon atoms, hydrogen atoms, oxygen atoms and nitrogen atoms, with the proviso that R 3 comprises at least 2 carbon atoms; and R 4 , which are identical or different, are each chosen from hydrogen atoms, C 1 to C 10 alkyl groups and a direct bond to at least one group chosen from R 3 and another R 4 such that when said at least one group is chosen from another R 4 , the nitrogen atom to which both R 3 and R 4 are bonded forms part of a heterocyclic structure defined in part by R 4 —N—R 3 , with the proviso that at least 50% of all R 4 are chosen from hydrogen atoms; (ii) fibers; and (iii) at least one compound chosen from at least one polysaccharide resin and at least one copolymer film former chosen from di-block, tri-block, multi-block, and radial copolymers, wherein said at least one heteropolymer is present in an amount effective to disperse said fibers.
