plastics always include carbon and hydrogen. While plastics may be made from just about any organic polymer, most industrial plastic is made frompetrochemicals. Thermoplastics and thermosetting polymers are the two types of plastic. The name "plastic" refers to the property ...
The vulcanization of rubber was another big achievement in polymer chemistry. German chemist Friedrich Ludersdorf (1801–1886) and American inventor Nathaniel Hayward (1808–1865) independently found addingsulfurto natural rubber helped keep it from becoming sticky. The process of vulcanizing rubber by ...
In this lesson, we will explore polymers, which are found everywhere, from our food to our clothes. You'll learn the definition of the term 'polymer,' and we'll look at examples of man-made and natural polymers. What are Polymers? Have you ever heard the tale of The Three Little ...
Cellulose nitrate is derived from the cellulose that makes up plant cell walls; it is so combustible it can be used in place of gunpowder. Rayon fiber, or cellulose acetate, is used to make a variety of yarns and fabrics. Plastics: Polymer Examples The most common, and famous, of the sy...

Chemistry, the science of the properties, composition, and structure of substances (defined as elements and compounds), the transformations they undergo, and the energy that is released or absorbed during these processes. Chemistry is concerned with the
A polymer is a very large, chain-like molecule made up of monomers, which are small molecules. It can be naturally occurring or synthetic.
In Batteries Batteries contain a variety of electrodes, depending on the battery type. Lead-acid batteries are based on lead electrodes. Zinc-carbon batteries are made with zinc and amorphous carbon electrodes. Lithium polymer batteries have electrodes made of a solid polymer matrix within which lith...
