Abstract

Maqolada ikkilamchi polietilentereftalat (VPET) va dietilenglikol (DEG) asosida olingan alkogoliz mahsuloti (PAPET) bilan modifikatsiyalangan plyonka markali polietilen (F-Y957, F-Y346, F-0120) namunalarining IQ-spektroskopik (FTIR) tahlili va fizik-mexanik xossalari o‘rtasidagi bog’liqlik ko‘rib chiqilgan. FTIR spektrlarida 1714-1745 sm⁻¹ sohasida kuzatilgan karbonil (C=O) yutilish polosasi PAPET tarkibidagi teraftalat ester fragmentlarining PE matritsasiga muvaffaqiyatli kiritilganini tasdiqlaydi, 2914-2916 va 2848-2849 sm⁻¹dagi CH₂ valent tebranishlari va 717-731 sm⁻¹dagi kristall PE dubleti esa asosiy polietilen zanjiri saqlanib qolganini ko‘rsatadi. Tarkibiy tahlil natijalari fizik-mexanik sinov ma’lumotlari bilan solishtirilib, PAPET miqdori va VPET:DEG nisbati oshishi bilan plyonka markali PE namunalarida elastiklik moduli, zarba mustahkamligi va ESCR ko‘rsatkichlarining nomonoton (bir tekis bo‘lmagan) o‘zgarishi tarkibiy geterogenlik bilan bog’liq ekanligi ko‘rsatildi.
