Study Notes
Polymer Types in Solid State
- Molecular solids are not a type of polymer in the solid state.
Crystalline Polymers
- Main characteristic: Ordered arrangement of molecules in a crystal lattice.
Amorphous Polymers
- Main characteristic: Disordered arrangement of molecules, lacking a crystal lattice.
Semi-Crystalline Polymers
- Characterized by having both crystalline and amorphous regions.
- Exhibits a combination of ordered and disordered molecular structures.
