Patent ID: 8053498

Claim:
A pulverulent polycondensation product essentially comprising: a) 5 to 95% by weight of a polycondensation product comprising an aromatic or heteroaromatic ring compound (A), wherein said ring has from 5 to 10 atoms selected from the group consisting of carbon atoms and heteroatoms, wherein said aromatic or heteroaromatic ring compound (A) has at least one oxyethylene or oxypropylene radical bonded to said ring, a compound (B) which is selected from the group consisting of an aromatic compound and an aminoplast former; wherein the compound (B) contains a substituent selected from only the group consisting of OH, NH 2 , OR 2 , NHR 2 , NR 2 R 2 , COOH, C 1 -C 4 -alkyl, PO 3 H 2 and OPO 3 H 2 , wherein the alkyl radicals can in turn have phenyl or 4-hydroxyphenyl radicals and R 2 is a C 1 -C 4 -alkyl radical or a (poly)oxy-C 2 -C 3 -alkylene radical which can contain a substituent selected from the group consisting of OH, COOH, PO 3 H 2 and OPO 3 H 2 ; and at least one aldehyde (C) selected from the group consisting of formaldehyde, glyoxylic acid, benzaldehyde, benzaldehydesulphonic acid and benzaldehydedisulphonic acid, or a mixture thereof, and b) 5 to 95% by weight of a finely divided mineral carrier material having a specific surface area of 0.5 to 500 m 2 /g according to BET as specified in DIN 66 131.
