  • Non-primary hydroxyl group based foams
    Publication number: 20230108069
    Abstract: Foamed pellets contain a thermoplastic polyurethane obtainable or obtained by a process. The process involves reacting a polyol composition (PZ-1) containing at least one hydroxy functionalized polyol (P1) with a maximum of 20% of primary hydroxyl groups with a polyisocyanate (I1), to obtain a polyol composition (PZ-2) containing a prepolymer (PP-1). The process then involves reacting the polyol composition (PZ-2) containing the prepolymer (PP-1) with a composition (C2) containing a chain extender (CE) with a molecular weight<500 g/mol. Foamed pellets are obtained or obtainable by the process. The foamed pellets can be used for the production of a molded body.
