Study Notes
Types of Polymers
- Homopolymer: consists of relatively long sequences of identical monomeric units
- Copolymer: consists of a mixture of more than one type of monomer
Physical Properties of Polymers
- Thermoplastic: softens on heating and can be converted to any shape by molding
- Isotactic polymer: a polymer in which the side groups of the monomers are arranged on the same side of the chain
- Thermoset: softens on heating, but does not become plastic and moldable
Definition and Terminology
- Polymer: a large molecule composed of many smaller molecules (monomers) bonded together
- Degree of polymerization: the number of monomer units in a polymer chain
Natural Polymers
- Biopolymer: includes proteins, cellulose, and silk
Natural vs Synthetic Polymers
- Main difference: source of origin (natural: occurs in nature, synthetic: produced by humans)
Role of Chemists
- About 80% of today's chemists, including biochemists, work on developing and improving polymers
