Web(g) Poly(phenylethene) is insoluble in water. Other polymers, such as poly(ethenol), can dissolve in water. repeating unit of poly(ethenol) CH 2CH OH Poly(ethenol) forms hydrogen bonds between its chains. Poly(phenylethene) forms instantaneous dipole–induced dipole bonds between its chains. In polymer chemistry, a repeat unit or repeating unit (or mer) is a part of a polymer whose repetition would produce the complete polymer chain (except for the end-groups) by linking the repeat units together successively along the chain, like the beads of a necklace. A repeat unit is sometimes called a mer (or mer unit). "Mer" originates from the Greek word meros, which means "a part". The word polymer derives its meaning from this, which means "many mers…
