ABSTRACT:
Pulverulent polycondensation products are described, consisting ofa) 5 to 95% by weight of a polycondensation product based on an aromatic or heteroaromatic compound (A) having 5 to 10 C atoms or heteroatoms having at least one oxyethylene or oxypropylene radical and one aldehyde (C) selected from the group consisting of formaldehyde, glyoxylic acid and benzaldehyde or mixtures thereof, andb) 5 to 95% by weight of a finely divided mineral carrier material having a specific surface area of 0.5 to 500 m2/g (according to BET as specified in DIN 66 131).The pulverulent polycondensation products according to the invention are outstandingly suitable in construction material mixtures in an amount of from 0.1 to 5% by weight, based on the weight of the construction material. The pulverulent polycondensation products have a number of advantages here, such as, for example, excellent storage stability, good liquefying action at low dosage and industrially simple production.
