Abstract (en)
[origin: DE102006009079A1] Carbonylhydrogenated ketone-aldehyde resin (I), based on formaldehyde with free formaldehyde of less than 3 ppm, is new. Carbonylhydrogenated ketone-aldehyde resin (I) of formula (I-a) to (I-c), based on formaldehyde with free formaldehyde of less than 3 ppm, is new. R : 6-14C aromatic or 1-12C (cyclo)aliphatic; either k : 2-15 (preferably 4-12); and m : 0-13 (preferably 0-9); and l : 0-2; or k+l+m : 5-15 (preferably 5-12); and Ra : H or CH 2OH. Provided that k is greater than m; and the structure elements are connected by CH 2-group and/or CH group. Independent claims are included for the preparations of (I). [Image].
