The invention relates to a process for preparing an alkoxylated product. The aim of the invention is to provide aromatic polyols for preparing polyurethane-based and polyisocyanurate-based polymers, which ensure good miscibility with the isocyanate component and other components, have a good storage stability and render the end product flameproof. For this purpose, the invention devises a process for preparing an alkoxylated product by. reacting bisphenol F with propylene carbonate and/or propylene oxide as propoxylation agent and ethylene carbonate and/or ethylene oxide as ethoxylation agent, the propoxylation agent and the ethoxylation agent being used in a molar ration of 70:30 to 45:55.

Process for production of an alkoxylated product

The invention relates to a composition containing a novolak and water. In one embodiment, a composition is provided comprising novolak and water with the percentage of ortho linkages of the phenol rings of the novolak is greater than that of para linkages, the novolak having a phenolic compound and an aldehyde molar ratio of from 1:0.2 to 1:0.45 and the composition having from 2% to 20% by weight of water based on the weight of the sum of the novolak and the water.

Composition containing a novolac

The invention relates to a composition for the production of foams based on phenolic resin, use thereof, and a process for the production of the composition. For provision of a composition for the production of foams based on phenolic resin, where the said composition delivers improved reaction to fire with, in essence, no alteration of further important foam properties, it is proposed that the composition comprises an alkoxylated novolak, wherein the novolak is produced using phenol, cresol and/or xylenol.

Compositions for producing foamed materials

Esterified arylhydroxy compounds for the production of polyurethane or polyisocyanurate. In order to provide aromatic polyols for the production of polyurethanes or polyisocyanurates which are process-technically suitable in terms of their viscosity and at the same time give the end product good physical properties and a good reaction to fire, esterified arylhydroxy compounds are proposed as polyols.

Modified arylhydroxy compounds for the production of polyurethane or polyisocyanurate

The invention relates to a composition that contains a binary mixture of bisphenol F and propoxylated bisphenol F. The aim of the invention is to provide aromatic polyols for preparing polyurethane-based and polyisocyanurate-based polymers, which ensure good handling from a technical point of view and good miscibility with the isocyanate component and render the end product flameproof. For this purpose, the invention devises a composition, which contains a binary mixture of ethoxylated bisphenol F and propoxylated bisphenol F in a weight ratio of 20:80 to 80:20.

Composition containing modified bisphenol F
