Structure and properties of drawing grade coal-based polypropylene and petroleum-based polypropylene
“In the field of polypropylene, researchers have systematically analyzed the effects of different sources of propylene on the structural characteristics and properties of drawing grade polypropylene, providing reference for product development and application. The results showed that the 5 types of PP can basically meet the requirements of the drawing material index, and their molecular weight and molecular weight distribution are independent of the source of propylene. The shear thinning amplitude and polydispersity index both increase with the increase of molecular weight distribution.”
