    Abstract: Syntactic polyurethanes are obtainable by reacting a polyisocyanate component a) with a polyol component, the polyol component b) comprising a polyetherpolyol mixture having an average OH number of from 10 to 280 (constituent b1) and an oil based on fatty acids of 6 to 25 carbon atoms or derivatives thereof (constituent b2), in the presence of hollow microspheres c). Furthermore, the syntactic polyurethanes are used for insulating offshore pipes and other parts and equipment used in the offshore sector, and the insulated offshore pipes as such are described.

    Abstract: Isocyanate adducts (I) made by reacting polyisocyanate(s) with compounds containing at least 2 NCO-reactive hydrogens, showing a crystallinity of less than 10 J/g by DSC, and an aromatics content of less than 31 wt.%, given as carbon atoms in aromatic rings. An Independent claim is also included for a method for the production of (I) by reacting (a) at least difunctional isocyanates with (b) compound(s) with at least 2 NCO-reactive H atoms in presence of (c) catalysts, in which (b) comprise (bi) polyether-polyol(s) with a functionality of more than 2.5 and a mol. wt. of more than 300 (preferably 300-1000) and (bii) polyol(s) with a functionality of 1.7-3 and a mol. wt. of more than 1000, and the reaction is carried out with an isocyanate index of less than 200.
