Natural polymers occur ready-made in living organisms: starch, a glucose polymer stored by plants as food reserve, and natural rubber, an isoprene polymer produced as latex by the rubber tree, are two clear examples (cellulose and the fibrous proteins silk/wool are further examples). Synthetic polymers are manufactured entirely from small organic monomers: polythene, made from ethene by addition polymerization, and nylon-6,6, made by condensing hexamethylenediamine with adipic acid, are two clear examples (PVC, terylene and bakelite are further examples).
✓Final answer
Natural: starch, natural rubber. Synthetic: polythene, nylon-6,6.
