Synthetic polymers are a class of human-made compounds that consist of chains and networks of repeating units. Typical examples include polyethylene (PE), polyvinyl chloride (PVC), polyamide (e.g., nylon), polyacrylate (e.g., adhesives), and polyester (e.g., PET). You will find that a very large portion of the things in your daily life is made of synthetic polymers. Without synthetic polymers, we would not have laptops, phones, bottles, a variety of textiles, and so much more. Source: https://theory.labster.com/synthetic_pvc/ Karawang, April 30, 2025 Ir.

N ext, I took a stroll down Michigan Avenue, also known as the Magnificent Mile. The array of shops, restaurants, and historic buildings was overwhelming in the best way possible. I treated myself to a delicious deep-dish pizza at Giordano's, which lived up to all the hype. As the day came to an end, I walked along the Chicago Riverwalk.
