polymer

[pol-uh-mer]

noun

Chemistry.

1. a compound of high molecular weight derived either by the addition of many smaller molecules, as polyethylene, or by the condensation of many smaller molecules with the elimination of water, alcohol, or the like, as nylon.

2. a compound formed from two or more polymeric compounds.

3. a product of polymerization.

polymer

/ ˈpɒlɪmə, ˈpɒlɪmə-, pəˈlɪməˌrɪzəm /

noun

1. a naturally occurring or synthetic compound, such as starch or Perspex, that has large molecules made up of many relatively simple repeated units Compare copolymer oligomer

polymer

1. Any of various chemical compounds made of smaller, identical molecules (called monomers) linked together. Some polymers, like cellulose, occur naturally, while others, like nylon, are artificial. Polymers have extremely high molecular weights, make up many of the tissues of organisms, and have extremely varied and versatile uses in industry, such as in making plastics, concrete, glass, and rubber.

2. ◆ The process by which molecules are linked together to form polymers is called polymerization (pŏl′ə-lĭm′ər-ĭ-zā|||PRIMARY_STRESS|||shən).

polymer

1. In chemistry, a long molecule made up of a chain of smaller, simpler molecules.

Proteins and many carbohydrates, such as cellulose, are polymers. Plastics are also polymers.
