WebPolypropylene (PP) is one of the most widely used general plastics, firstly synthesized by professor Natta in 1954, and then gradually manufactured in industries, thus establishing a new chapter in polymer science and engineering (Zheng et al., 2024).PP belongs to the group of thermoplastics, and it is obtained by polymerizing propylene gas, using the … A polymer is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fun…
