“…As a kind of thermoplastic resin with excellent performance, poly(ethylene terephthalate) (PET) has been widely used in the production of textile fibers, − packaging films, , and beverage bottles. − However, it still has disadvantages such as a low crystallization rate and difficult molding process, which have always limited its application prospect in other fields. − In addition, the viscosity, melt strength, and mechanical properties of PET are closely related to its molecular weight. Lowering the molecular weight of PET during the thermal, chemical, and oxidative degradation limits its use in other fields such as recycling and reprocessing. − …”

In this work, poly(ethylene terephthalate) (PET) chain-extending products with different molecular weights were prepared by reactive extrusion using isocyanate trimer (C-HK) as the trifunctional chain extender. The effect of the chain extender C-HK on the intrinsic viscosity, melt flow property, crystallization behavior, crystallization morphology, and mechanical property of PET was investigated. The results showed that when the content of the chain extender was increased from 0.6 to 1.4 wt%, the viscosity average molecular weight of PET was effectively increased from 2.36 × 10 4 to 5.46 × 10 4 g·mol –1 . After the chain extending, the crystallinity and the time of semicrystallization of PET were significantly decreased. After the isothermal crystallization at 220 °C for 5 min, the spherulites formed by pure PET became larger. With the increase in molecular weight of PET after chain extension, its spherulite size was significantly decreased without changing the crystalline structure. The chain-extended PET also exhibited more excellent bending-resistant and impact-resistant properties. While the tensile strength of PET after chain extension was slightly decreased, the bending strength was increased by a maximum value of 56.8%, and the impact strength was increased by a maximum value of five times.
