Supplementary Information R 1 and R 2 are hydrocarbon groups. H Go to top . Supplementary Information Rl and R2 are hydrocarbon groups. O Go to top . A polymer is composed of many repeating units called monomers.
Polymerization is the process of joining monomers.
Polymers may be formed by condensation or by addition polymerization. Supplementary Information Starch, cellulose, and proteins are natural polymers. Nylon and polyethylene are synthetic polymers. Go to top . A. Condensation Understandings and Fundamental Concepts Condensation polymerization results from the bonding of monomers by a dehydration reaction.
