These substances also turn into a structure similar to a chain. Ethene is the unsaturated monomer which, when joined to other ethene molecules through an addition reaction, forms the saturated polymer polyethene. Neoprene is rapidly cross-linked by zinc oxide, so ZnO is typically the last ingredient added to a neoprene mix. Materials Science/Useful Formulas. Displayed formulas of polymers Polymer molecules are very large compared with most other molecules, so the idea of a repeating unit is used when drawing a displayed formula. Info. This polymer is called polyethylene rather than polymethylene, $$\ce{(-CH_2-)_{n}}$$, because ethylene is a stable compound (methylene is not), and it also serves as the synthetic precursor of the polymer. Which one of the following is the chemical formula for the repeating unit in polyethylene: (a) CH2, (b) C2H4, (c) C3H6, (d) C5H8, or (e) C8H8?
