Explanation:
Styrene is a member of a group of chemical compounds broadly categorized as vinyls organic compounds whose molecules contain a double bond between two carbon atoms. Under the action of chemical catalysts or initiators, this double bond can be opened, and one of the two resultant single bonds is then able to link to a carbon atom of another styrene molecule; this link contributes to the formation of polystyrene, in which thousands of styrene units are linked along a carbon backbone, thus making the formula become a molecular component.
