WebCommon aliphatic diols are ethylene glycol, 1,4-butanediol, and 1,3-propanediol. They are often reacted with aromatic diacids, such as terephthalic acid, phthalic acid, phthalic anhydride and naphthalene dicarboxylic acid. Glycerol and unsaturated acids (anhydrides) like maleic anhydride, are sometimes added to crosslink the polyesters.
