Abstract:
1. A process, comprising: (A) reacting naphthylene 1,5-diisocyanate (NDI) (a) with a polyether alcohol (b), to obtain a prepolymer, and (B) reacting, in a mold, the prepolymer obtained in said reacting (A) with a crosslinking component comprising water, to obtain a cellular polyisocyanate polyaddition product, where the polyether alcohol present in the reacting (A) comprises three different aliphatic polyether alcohols: (b1) an aliphatic polyether alcohol having a number-average molar mass of from 300 to 1000 g/mol, (b2) polytetrahydrofuran whose number-average molar mass is from 2000 to 10,000 g/mol, and (b3) an aliphatic polyether alcohol having a number-average molar mass of from 10,000 to 100,000 g/mol.
