PROBLEM TO BE SOLVED: To provide a material which can be easily used, while at the same time maintains good impact strength, rigidity and flame-retardance, and whose polymer matrix structure comprises a unit from a raw material originating from biomass.SOLUTION: There is provided a composition comprised of the following (1) to (3) having the following percentage relative to the total weight of the composition. (1) 25 to 52 wt.% of at least one kind of a semi-crystalline or an amorphous polyamide having an amine chain- end content of 0.040 meq/g or less. (2) 24 to 40 wt.% of at least one kind of a reinforcer. (3) 24 to 35 wt.% of at least one kind of metal optionally contained in the polymer, chosen from a metal salt of phosphinic acid, a metal salt of diphosphinic acid and a mixture thereof. The polyamide contains at least 50 wt.% of an organic carbon generated from biomass determined according to ASTM standard D6866. |
