Effect of poly(ethylene terephthalate) and polyethylene comminution on the mechanical and thermal properties of polymer compositions
Abstract
Comparative study has been done on the effect of comminution of poly(ethylene terephthalate) (PET) and low density polyethylene (PE-LD) granulated products (NRG-not comminuted granulates, RG-comminuted granulates) on the properties of these polymers blends (in the range up to 15 wt. % of disperse phase) as well as individual polymers. The values of melting point (Tm), glass transition temperature (Tg) and crystallinity degree (X) of the polymers (Table 2-5, Fig. 2-5) were characterized by DSC method. The chemical structure (Fig. 6-9) was evaluated by IR method while morphology was characterized by SEM method. Additionally, the mechanical properties of samples (tensile strength and elongation, Young’s modulus, notched impact strength - Table 6 and 7) were determined. It has been found that comminution significantly influence the chemical structure and mechanical properties. It is the rule the mechanical properties improve.
