This disclosure describes various poly(acetal) polymers including processable, elastomeric poly(acetals). Various polymers described herein have a chemical structure containing cyclic acetal monomer units derived from diglycerol and a dialdehyde compound. The disclosure also relates to a method of preparing such polymers. The method can involve heating and/or adding acid to a mixture containing diglycerol and a dicarbonyl compound so as to obtain an elastomeric polymer.

Poly(acetal) elastomers

Ionomers comprising ionic groups such as, for example, tetraalkylammonium groups and methods of making such ionomers. For example, the ionomers can be produced by ring opening metathesis polymerization of alkene-containing monomers with tetraalkylammonium groups and, optionally, alkene-containing monomers without tetraalkylammonium groups. The ionomers can be used in applications such as, for example, fuel cell applications.
