Polymers are made of repeating organic/inorganic monomer units. In polymer chains the carbon atoms are bonded together, due to the nature of carbon, one or more other atoms can be attached to each carbon atom in the backbone chain. Polyethylene (PE) is made from ethylene which only has carbon and hydrogen atoms, while polyvinyl chloride (PVC) has chlorine attached to the all-carbon backbone. customized polymerization https://www.matexcel.com/servi....ces/polymer-manufact
