What is a linear polymer?

A linear polymer is a long, continuous chain of carbon-carbon bonds with the remaining two valence bonds attached primarily to hydrogen or a different small hydrocarbon moiety. It is the simplest polymer and it exists as a single straight line of carbon-carbon bonds. When formed, linear polymers can make strands of fibers or form a mesh that is very strong and hard to break. Some common examples of linear polymers are Teflon and polypropylene. 

Additional characteristics of linear polymers are listed in the bulleted points below.   

• Its chain may or may not be made of pendant groups.
• Has no branching.
• Is tightly packed.
• Is high density.
• Has a high melting and boiling point.
