The invention concerns a transparent polyamide alloy, produced by compounding it from 30-98% by weight of a transparent, amorphous, rigid and brittle polyamide A with at least 35 mole % cyclo-aliphatic diamine and a glass transition point of at least 150° C., and 2-70% by weight of a transparent, impact resistant polyamide B with at least 40-80 mole % of at least one long-chain polyamide-forming monomer, with more than 10 carbon atoms and at least 10 mole % terephthalic acid and a glass transition point of under 70° C.
本发明涉及一种透明聚酰胺合金,它是由 30-98% (重量百分比)的透明、无定形、硬而脆的聚酰胺 A 和 2-70% (重量百分比)的透明、抗冲击的聚酰胺 B 复配而成,前者含有至少 35 摩尔%的环脂族二胺,玻璃化转变点至少为 150 摄氏度,后者含有至少 40-80 摩尔%的至少一种长链聚酰胺形成单体,其碳原子数超过 10 个,对苯二甲酸含量至少为 10 摩尔%,玻璃化转变点低于 70 摄氏度。
