Webb10 aug. 2024 · Polymers. Polymers in the form of thermo-plastics (nylon, polyethylene, polyvinyl chloride, rubber, etc.) consist of molecules that have covalent bonding within each molecule and van der Waals forces between them. Polymers in the form of thermo-sets (e.g., epoxy, phenolics, etc.) consist of a network of covalent bonds. WebbHigh temperature thermoplastics (as all polymers) comprise two molecular structures: amorphous (randomly ordered) and crystalline (highly ordered). For practical purposes, thermoplastics are either amorphous polymers or semi-crystalline polymers which have both amorphous and crystalline regions. new windows by anderson
