Semi-crystalline polyoxymethylene-\(\it co\)-polyoxyalkylene multi-block telechels as building blocks for polyurethane applications
- Hydroxy-terminated polyoxymethylene-\(\it co\)-polyoxyalkylene multi-block telechels were obtained by a new methodology that allows for the formal substituting of ether units in polyether polyols with oxymethylene moieties. An interesting feature is that, unlike carbonate groups in polycar-bonate and polyethercarbonate polyols, homopolymer blocks of polyoxymethylene moieties can be formed. The regular nature of polyoxymethylene blocks imparts a certain crystallinity to the polymer that can give rise to new properties of polyurethanes derived from such telechels. The synthesis, reaction sequence and kinetics of the formation of oligomeric hydroxy-terminated mul-ti-block telechel polyoxymethylene moieties are discussed in this paper and the preparation of a polyurethane material is demonstrated.
