    Abstract: A cellular polyisocyanate-polyaddition product (I), having a density of 250-900 kg/m , contains an ester (II) that has no groups that are reactive with isocyanate and is based on carboxylic acids having at least 2 carboxyl groups and alcohols having 2-5 hydroxyl groups. Independent claims are included for (i) shoe soles, shoe parts, dampening elements and/or rollers containing the cellular product (I).
