Abstract: The invention relates to a process for the preparation of boron-containing phenol/formaldehyde resins be reacting diphenylol alkane novolaks with unsaturated fatty acids or fatty acid esters and boron compounds, characterized in that diphenylol alkane novolaks having a molecular weight of from 400 to 1600 are reacted with from 15 to 35 parts by weight of an unsaturated fatty acid or its esters, accompanied by the azeotropic removal of water, and then with from 20 to 100 parts by weight of a boric acid trialkyl ester containing from 1 to 4 carbon atoms per alkyl group or with 14 to 72 parts by weight of a boric acid alkyl ester anhydride of the general formula (RO)2 B-O-B-(OR)2 with 1 to 4 carbon atoms per alkyl group R or with from 10 to 50 parts by weight, preferably from 15 to 20 parts by weight of boron trioxide or with from 18 to 90 parts by weight, preferably from 25 to 36 parts by weight of boric acid in the presence of a C1-C4 alcohol.

Abstract: Resins having a softening point of from 50 DEG to 130 DEG C., an OH-number of from 250 to 400 and an iodine number of from 90 to 160, obtainable by reacting an alkyl phenol-formaldehyde novolak or an alkyl phenol mixture-formaldehyde novolak under acid-catalysed conditions with a polunuclear phenol or polynuclear phenol mixture and formaldehyde and/or an aliphatic aldehyde or aliphatic aldehyde mixture, the ratio by weight of the alkyl phenol or alkyl phenol mixture to the polynuclear phenol or polynyclear phenol mixture being from 2.2:1 to 1:10.
