This document introduces polymers and provides a classification system based on origin, structure, molecular forces, and polymerization. Natural polymers include those that occur in nature, while synthetic polymers are obtained through chemical modification of natural polymers. Polymers can have linear, branched, cross-linked, or network structures. They are also classified as elastomers, fibers, or other categories based on their molecular forces. Polymerization can occur through addition or other chemical reactions.
