Kugirango twige imyitwarire ya kristu ya kirisiti hamwe nimiterere ya PA66 yahinduwe nubwoko butandukanye bwa sem-aromatic copolymerized nylon resin, ubwoko butandukanye bwa sem-aromatic copolymerized nylon resin bwongewe kuri resin ya PA66, hamwe ningaruka zubwoko butandukanye nibirimo igice cya aromatic copolymerized nylon resin kumyitwarire ya kristallisation hamwe nimiterere ya alloy mate‐ rials yarizwe.Ibisubizo byerekana ko ubwoko butandukanye bwa sem-aromatic copolymerized nylon resin ifite imyitwarire itandukanye yo gutegera hamwe nibintu byiza mubivanze.Hamwe no kwiyongera kwa poly-m-xylyleneadipamide (MXD6), ubushyuhe bwo gushonga (T_m) n'ubushyuhe bwa kristu (T._c.Iyo umubare wongeyeho polyphthalamide (PA6T / 6) urenze cyangwa uhwanye na 40% yibigize resin, imyitwarire ya kristu yo kuvanga itangira guhinduka kuburyo bugaragara, gukomera no guhindura ubushyuhe bwuruvange byiyongera, kandi gukomera ni yagabanutse.Hamwe no kwiyongera kwa PA6T / 6, kwinjiza amazi kuvanze bigabanuka, kandi ubucucike bugira ingaruka nke.Iyo umubare wongeyeho poly (p-phenyl-pentadiamine) (PA5T) urenze cyangwa uhwanye na 30% yibigize resin, PA5T itangira kugira uruhare mukuvanga, gukomera biragabanuka, kwinjiza amazi biragabanuka.Amazi yinjira mumavange yabanje kugabanuka hanyuma akiyongera hamwe no kwiyongera kwa PA5T, kandi umubare wongeyeho PA5T ntacyo uhindura kubucucike bwuruvange.Iyo ingano ya polydecamethylene terephthalate (PA10T) iri munsi ya 40% yibigize resin, T_m na T._c y'uruvange rugabanuka gahoro gahoro, ubukana hamwe nubushyuhe bwumuriro mc wuruvange byongerewe imbaraga, kandi ubukana buragabanuka.Kwinjiza amazi kuvanga bigabanuka hamwe no kwiyongera kwa PA10T.Iyo yongerewe kugera kuri 50% yibigize resin, kwinjiza amazi ntibikigabanuka, kandi gukomera no guhindura ubushyuhe ntibikiriyongera.
