Abstract: This study investigated the impact of incorporating a 1‑3% by weight of biodegradable additive into polypropylene (PP) using twin‑screw extrusion, followed by injection molding to prepare test specimens. The effects of the additive on the rheological, thermal, mechanical, and optical properties of PP were investigated, along with the impact of two common sterilization methods: autoclave (121°C, 15 min, 0.11 MPa) and electron beam (E-Beam, 50 kGy) irradiation. The results showed …
