they are large organic molecules, macromolecules, made of smaller repeating molecular units called monomers joined by covalent bonds
thermoplastics soften when heated and harden when cooled down, thermosets harden the first time they are heated and never soften again
the more crystalline (defined pattern) the polymer, the stronger and flexible it becomes, amorphous polymers are randomly arranged
