摘要
Single-phase and amorphous polymeric mixtures capable of being employed especially for producing shaped articles using moulding operations. According to the invention the said mixtures comprise: (i) an amorphous semiaromatic polyamide obtained from 2-methyl-1,5-pentamethylenediamine taken by itself or mixed with 2-ethyl-1,4-tetramethylenediamine and isophthalic acid taken by itself or mixed with terephthalic acid, and (ii) a semicrystalline polyamide of the nylon type chosen from the group made up of nylon 66, nylon 6, mixtures of these polymers and the copolymers obtained from monomers resulting in these nylons, the quantity of the semicrystalline polyamide of the nylon type (ii) representing not more than 40% of the weight of the combined semiaromatic polyamide (i) + semicrystalline polyamide (ii). The resilience properties of the semiaromatic polyamide at temperatures ranging from room temperature to -25 DEG C can be improved with such mixtures.
