The present invention relates to a phosphorus containing polyol, obtainable or obtained by a process comprising the reaction of at least one polyol with a phosphorus containing compound of the general formula (I) as defined herein, as well as the process for preparing a phosphorus containing polyol, comprising the reaction of at least one polyol with a phosphorus containing compound of the general formula (I). Furthermore, the present invention relates to the use of a phosphorus containing polyol as disclosed herein as a flame retardant, to a process for the preparation of a polyurethane and the polyurethane as such. 

Phosphorous containing flame retardants

A multilayer composition for packaging comprising a first polymer film, a second film, at least one print layer between the films and a 1 K isocyanate prepolymer adhesive layer between the at least one print layer and one of the films, where the print layer contains a hyperbranched polyester binder containing functional groups selected from the group consisting of &#x2014;OH, &#x2014;COOH and &#x2014;COOR, where R is methyl, ethyl, vinyl, isopropyl, n-propyl, n-butyl, isobutyl, sec-butyl or tert-butyl provides packaging laminates with excellent adhesion. The hyperbranched polyester is for example a polymer of trimethyolpropane and hexahydrophthalic anhydride and optionally a cycloaliphatic diol.

Multilayer composition for packaging

The present invention relates to a polyurethane composite system comprising a rigid polyurethane foam and a coating material composed of a compact polyurethane or a compact polyurea, wherein the rigid polyurethane foam comprises a porous three-dimensional reinforcing material which forms a network, where the network encloses at least 50% of the volume of the rigid polyurethane foam, or at least two layers of a porous, at least two-dimensional reinforcing material. The present invention further relates to a process for producing the polyurethane composite system and also a sports article, cladding part or furniture item comprising such a polyurethane composite system.

Polyurethane composite system having high compressive strength and rigidity

The present invention relates to polyester polyols based on aromatic dicarboxylic acids and their use for producing rigid polyurethane foams.

Polyester polyols based on aromatic dicarboxylic acids

The present invention relates to a rigid polyurethane foam which can be obtained by mixing (a) isocyanates, (b) compounds having groups which are reactive toward isocyanates, (c) blowing agents comprising water, (d) catalysts and optionally (e) further additives to form a reaction mixture, applying the reaction mixture to a reinforcing material and curing the reaction mixture, where the isocyanates (a) have a viscosity of not more than 500 mPas at 25&#xb0; C. and the compounds (b) having groups which are reactive toward isocyanates comprise a polyetherol (b1) having a functionality of 4 or more and a viscosity at 25&#xb0; C. of 10 000 mPas or less, a polyetherol (b2) having a functionality of 3.5 or less and a viscosity at 25&#xb0; C. of 600 mPas or less, a polyesterol (b3) having a viscosity at 25&#xb0; C. of 2000 mPas or less, chain extenders (b4) comprising at least 30% secondary OH groups and optionally a crosslinker (b5). The present invention further relates to a process for producing such rigid polyurethane foams and the use of the rigid polyurethane foams for the insulation of liquefied natural gas tanks.

Water-blown rigid foams with improved mechanical properties at low temperatures

The use of at least one diphosphine of formula (I), wherein

Derivatives of diphosphines as flame retardants for polyurethanes

The present invention relates to a sheet-like construction element composed of composite material, comprising two metallic outer layers, a rigid polyurethane foam layer, and a compact polyurethane layer which comprises microcapsules with a capsule core composed of latent-heat-accumulator material, and also to a process for its production, and to its use.
