摘要： The invention relates to a method of making a polymer-modified polyol having a solid content from 13 to 55 wt. % wherein an olamine is reacted with an organic polyisocyanate in the presence of a base polyol and at least one catalyst, wherein said at least one catalyst is a zinc carboxylate, and wherein the base polyol has hydroxyl functions wherein more than 20% of said hydroxyl functions are primary hydroxyl functions. The invention further relates to a polymer-modified polyol obtainable with the method of the invention, the use of the polymer-modified polyol for the preparation of optionally foamed plastics, and to a method for the preparation of optionally foamed plastics using the polymer-modified polyol of the invention.

摘要： The invention relates to a process for the preparation of a triaryl phosphate ester composition comprising a. reacting a phosphorous oxyhalide with a (C1-C15-alkyl)phenol to obtain a first product; b. reacting the first product with phenol to obtain a triaryl phosphate ester composition; wherein in step a., for every mol of phosphorous oxyhalide 1.3 to 1.6 mols of (C1-C15-alkyl)phenol are used. The invention also relates to a triaryl phosphate ester composition obtainable according to the process of the invention.

摘要： The invention relates to a process for preparing a flame-resistant polymer-modified polyol having a solids content of 1 to 65 wt. % wherein (i) at least one polyisocyanate and (ii) an olamine are reacted in (iii) a base polyol having at least two active hydrogen containing groups of which more than 50% are primary active hydrogen containing groups and wherein the olamine has at least one phosphonic ester group attached to a tertiary nitrogen atom and contains at least two hydroxyl groups. The invention further relates to a flame-resistant polymer-modified polyol obtainable with the process of the invention, to a process for preparing optionally foamed plastics using the polymer-modified polyol of the invention, and to the use of a polymer-modified polyol for the preparation of flexible polyurethane foams.
