Abstract: Polyurethane with a loss factor of 0.2-0.8 is based either on (a) a prepolymer obtained by reacting a polyisocyanate with a polyester polyol or polyether polyol with secondary hydroxyl group(s) and a molecular weight of 300-1200 or; (b) a polyol component containing other polyester polyol(s) or polyether polyol(s) with primary and secondary OH groups and a molecular weight of 300-1200. A process for the production of polyurethane (PU) with a loss factor of 0.2-0.8 involves bringing into contact (A) a component containing compound(s) which react with isocyanate and (B) a polyisocyanate component. In this system, either (1) component (B) is a prepolymer obtained by reacting a first polyester polyol or polyether polyol with at least one secondary hydroxyl group and a number-average molecular weight (MW) of 300-1200, or at least two of these, with an NCO group-containing compound, or; (2) component (A) contains other polyester polyol(s) or polyether polyol(s) with primary and secondary OH groups and MW of 300-1200. Independent claims are also included for (i) PU obtained by this process, with a loss factor of 0.2-0.8 and also with a natural frequency of 30-500 Hz and/or a dynamic elastic modulus of 1-50 N/cm ; (ii) a method for obtaining PU with a loss factor in the above range or also with at least one of the other properties in (i), by incorporating polyester polyol(s) or polyether polyol(s) with MW in the above ranges into the PU; (iii) formed articles containing PU as in (i).

Abstract: Production of rigid polyurethane (PUR) foam involves reacting (a) organic and/or modified organic di- and/or polyisocyanates with (b) special polyester-polyols (IA) and/or polyether-ester-polyols (IB) and optionally (c) chain extender and/or cross-linking agent in the presence of (d) blowing agent, (e) catalyst and optionally (f) other ancillaries and/or additives. (IA) and (IB) can be prepared by polycondensation of dicarboxylic acids with polyols using polyalkylene terephthalate (II) and, if necessary, reaction with lower alkylene oxide and optionally other higher molecular compounds with NOTLESS 2 reactive hydrogen atoms. The novelty is that the preparation of (IA) and/or (IB) is carried out by polycondensation in stages, with addition of (1) (II) to the starting materials at the beginning and/or during the first stage and (2) catalyst during other stage(s).
