High molecular mass macromolecules are called polymers which consist of repeating structural units derived from corresponding monomers. These polymers can be classified in a number of ways, such as based on their source, method of preparation intermolecular forces of attraction etc.
Natural rubber is a polymer of cis-1, 4-isoprene and can be made tough with vulcanisation process. Polymers are useful in manufacturing of various materials such as toys, fibres, pipes, television cabinets etc.
In view of potential environmental hazards of waste disposal certain biodegradable polymers are synthesised such as PHBV.
