Polymers have bonds
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… WebJul 7, 2024 · Advertisement They have relatively low melting and boiling points because there are weak (intermolecular) forces that act between the molecules. It is these weak forces and not the strong covalent bonds that are broken when the substance melts or boils. Do polymers have higher melting points than metals? Metals, ofRead More →
