polymer Scientific  

/ pŏl′ə-mər /

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 Cultural  

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

Explanation

A polymer is a very large, chain-like molecule made up of monomers, which are small molecules. It can be naturally occurring or synthetic. What's a mer? — you might ask. Well, it means "part," and it works only as a suffix. Since poly- means "many," a polymer means "many parts." You'll find polymers everywhere: they're what make spandex stretch and sneakers bounce. They're the plastic drink bottles that you're always careful to recycle. Natural polymers include leather, rubber, and even the cellulose in your french fries and the protein in your chicken nuggets.
