Polymers are composed of simple molecules called monomers.
<h3>What is a polymer?</h3>
A polymer is a macro molecule that is composed of smaller molecules called monomers which aggregate in repeating units having a well defined structure.
Organic polymers contain long chains of carbon and often occur in nature. The factors that the two organic polymer hypotheses have in common regarding how more complex organic polymers originated is that;
- Organic polymers originated from chemical changes in complex inorganic molecules
- Complex organic polymers resulted from aggregation of simple organic molecules.
