The present invention relates to a compound obtained by a process comprising the following steps: (i) Reacting at least one isocyanate containing compound, in stoichiometric excess, with at least one isocyanate-reactive compound having a number average molecular weight equal to or higher than 400, resulting in the formation of at least one prepolymer having soft blocks and hard blocks in its structure, which prepolymer contains unreacted isocyanate monomer, (ii) Reacting said at least one prepolymer with a hydroxyl-ester compound or a hydroxyl-acid compound with the formation of hydroxyl-ester terminated prepolymer or hydroxyl-acid terminated prepolymer, and Ring-closing said hydroxyl-ester terminated prepolymer or hydroxyl-acid terminated prepolymer; (iii) Formation of said compound made of oxazolidinedione-terminated prepolymer and oxazolidinedione-terminated monomer, which is soluble in said oxazolidinedione-terminated prepolymer.

Oxazolidinedione-terminated prepolymer

The present invention relates to a hybrid polyurethane-polyhydroxyurethane (PU-PHU) composition obtained by a process comprising the following steps:

Hybrid polyurethane-polyhydroxyurethane composition

A process for binding lignocellulosic material comprising the steps of a) bringing lignocellulosic material into contact with a methylene bridged polyphenyl polyisocyanate composition and b) subsequently allowing said material to bind wherein said polyisocyanate composition has a surface tension below or equal to 46 mN/m.

Process for binding lignocellulosic materials using polyisocyanate compositions

The invention relates to a formulation comprising: &#x2014;a first component which is formed from at least one isocyanate and at least one amino resin, wherein said amino resin is the condensation product of an aldehyde with a compound selected from the group comprising urea, melamine, benzoguanamine, glycoluril, acetoguanamine and mixtures thereof; and &#x2014;a second component comprising at least one polyether, wherein said polyether comprises at least one ethylene oxide moiety and at least one isocyanate reactive group selected from the group comprising hydroxyl, amino, epoxy, and thiol, preferably hydroxyl.
