Ukuze ufunde indlela yokwenza icrystallization kunye neepropathi zePA66 zilungiswe ziintlobo ezahlukeneyo zenayiloni enevumba elimnandi, iindidi ezahlukeneyo zentlaka enayiloni enevumba elimnandi zongezwa kwintlaka yePA66, kunye neziphumo zeentlobo ezahlukeneyo kunye neziqulatho zenayiloni enuka kamnandi. I-copolymerized nylon resin ekuziphatheni kwecrystallization kunye neepropathi zezinto ze-alloy zaphononongwa.Iziphumo zibonisa ukuba iintlobo ezahlukeneyo ze-semi-aromatic copolymerized resins zenayiloni zinesimilo esahlukileyo se-crystallization kunye nomxholo ofanelekileyo kwimixube.Ngokunyuka komxholo we-poly-m-xylyleneadipamide (MXD6), ubushushu obunyibilikayo (Tm) kunye nobushushu becrystallization (Tc) yokunciphisa ukudibanisa, ukuqina kunye nokuguqulwa kwe-thermal yokwanda kwe-blend, ukuqina kwe-mc kunye nokunciphisa ukufunxa kwamanzi, kwaye ukuxinana kunempembelelo encinci.Xa inani elongezelelweyo le-polyphthalamide (PA6T/6) likhulu okanye lilingana ne-40% yecandelo le-resin, ukuziphatha kwe-crystallization yomxube kuqala ukutshintsha kakhulu, ukuqina kunye nokuguqulwa kwe-thermal yomxube kuyaphuculwa, kwaye ukuqina kuncitshisiwe.Ngokunyuka komxholo we-PA6T / 6, ukuxutywa kwamanzi okuxutywa kuyancipha, kwaye ubuninzi bunempembelelo encinci.Xa inani elongezelelweyo le-poly (p-phenyl-pentadiamine) (PA5T) likhulu okanye lilingana ne-30% yecandelo le-resin, i-PA5T iqala ukudlala indima ekuxubeni, ukuqina kuyancipha, ukuxutywa kwamanzi kuyancipha.Ukuxutywa kwamanzi okuxutywa kuqala kuyancipha kwaye kwanda ngokunyuka komxholo we-PA5T, kwaye inani elongezelelweyo le-PA5T linempembelelo encinci kubuninzi bomxube.Xa inani le-polydecamethylene terephthalate (PA10T) lingaphantsi kwe-40% yecandelo le-resin, i-Tm kunye neTc yokudibanisa iyancipha ngokuthe ngcembe, ukuqina kunye ne-thermal deformation mc yomxube iyaphuculwa, kwaye ukuqina kuyancipha.Ukufunxwa kwamanzi okuxutywa kuyancipha ngokunyuka komxholo we-PA10T.Xa inyuswa ukuya kwi-50% yecandelo le-resin, ukuxutywa kwamanzi akusancitshiswa, kwaye ukuqina kunye nokuguqulwa kwe-thermal akusayi kuphuculwa.
