Abstract (en)

[origin: WO2008086555A1] The invention relates to phenol-formaldehyde resins, which can be obtained by the alkalinically catalyzed condensation of phenol and formaldehyde in the presence of at least one salt of inorganic acids, and neutralization following the condensation by means of an inorganic or organic acid. The production takes place by adding at least one compound of the formula R<SUP>1</SUP>-(CH<SUB>2</SUB>)<SUB>n</SUB>-R<SUP>2</SUP> (1), wherein R<SUP>1</SUP>, R<SUP>2</SUP> independently from each other are -C(O)R, -COOR, -CN or -NO<SUB>2, </SUB>wherein R is H or CH<SUB>3, </SUB>and n has the value of 1 or 2. Furthermore, the invention particularly relates to the production of said resins and the use thereof as binders for insulating products on mineral fiber basis.
