POLYAMIDE AND POLYAMIDE COMPOSITION |
摘要 |
[Problem to be Solved] A main object of the present invention is to provide a polyamide and a polyamide composition capable of rendering good surface appearance stability and outstanding impact resistance properties to a molded article even when molded under rigorous molding conditions. [Solution] The present invention is (A) a polyamide comprising (a) a unit comprising adipic acid and hexamethylenediamine and (b) a unit comprising isophthalic acid and hexamethylenediamine, wherein a ratio of the isophthalic acid component to the total carboxylic acid component in the polyamide is 0.05≦̸(x)≦̸0.5 and a range of blocking ratio (Y) is −0.3≦̸(Y)≦̸0.8. Also, the polyamide composition of the present invention contains 30 to 95% by mass of the above polyamide and 5 to 70% by mass of (B) an inorganic filler. |
