difference between polymer and plastic
Polymer vs Plastic. Polymers. Polymers are large molecules, which have the same structural unit repeating over and over. The repeating units are called monomers. These monomers are bonded to each other with covalent bonds to form a polymer. They have high molecular weight and consist over 10,000 atoms.
Plastic is also polymer, which has a large molecular mass. The monomers of plastic can be natural or synthetic. Plastic is synthesized from petrochemicals. Thermoplastics and thermosetting polymers are two types in plastics.
