Telechelic polyacetals, obtained by cationic ring‐opening polymerization of 1,3‐dioxolane (DXL) and 1,3‐dioxepane (DXP), have been used as building blocks for polymer materials. In the first part of this paper, the synthesis and the properties of networks based on polyDXL α,ω‐bis(methacrylates) are discussed. The second part deals with the synthesis and the properties of polyacetal polyurethanes. A thermoplastic polyurethane was prepared with poly(DXL‐co‐DXP) α,ω‐diol as soft segment and the combination butane‐1,4‐diol and hexamethylene diisocyanate as hard segment. Polyurethane networks were obtained from polyacetal polyols and diphenylmethane diisocyanate (MDI). Some physical properties of these new materials are reported.
