It prolongs dormancy of lateral buds and promotes apical dominance. Associate Professor of Chemistry, University of Virginia, Charlottesville. In addition to these compounds, ethylene and benzene combine to form ethylbenzene, which is dehydrogenated to styrene for use in the production of plastics and synthetic rubber. Polymerization (the repetitive joining of many small molecules into larger ones) of ethylene gives polyethylene, a polymer having many uses, particularly in the production of packaging films, wire coatings, and squeeze bottles. When the fruits are placed in paper bags, it concentrates the levels of ethylene gas which induces the ripening of the fruits. Ethylene chloride is produced by the reaction of ethylene and chlorine.
