The invention provides a polymer system, including a first composition and a second composition. The first composition is different from the second composition. The first composition includes a first gelator, the first gelator including a plurality of acylhydrazine moieties. The second composition includes a second gelator, the second gelator including a plurality of formyl moieties. At least one of the first composition and the second composition includes a prepolymer. The invention further provides a method of using the polymer system to form a polymeric material via multiple stages to more effectively control the rheology of the components over a variety of timescales.

Soft-to-hard transformation of the mechanical properties of dynamic covalent polymers through component incorporation
The mechanical properties of acylhydrazone dynamic polymers may be converted from soft to hard by the incorporation of rigid monomeric components into the original soft polymer backbone, taking advantage of acylhydrazone bond exchange.
