Claim:
A thermoplastic processible etherified aminoplast resin made by the steps of: (a) simultaneous conversion of at least one triazine compound with at least one aldehyde and at least one alcohol, wherein the triazine compound corresponds to the general formula (I) wherein R 2 means Q 1 or a moiety of the formula R 4 —N—R 5 connected with its central nitrogen atom to the triazine ring of the structure of formula (I), wherein Q 1 means a linear or branched C 1 -C 50 -alkyl or a cyclic substituent in form of a C 5 -C 20 -cycloalkyl, a C 5 -C 20 -aryl, a C 1 -C 20 -alkyl substituted C 5 -C 20 -aryl, C 2 -C 20 -heterocycle, C 2 -C 20 -alkenyl substituted C 2 -C 20 -heterocycle, C 1 -C 50 -alkyl substituted C 2 -C 20 -heterocycle, a C 2 -C 20 -alkenyl, a C 2 -C 20 -alkenyl substituted C 5 -C 20 -aryl, C 2 -C 12 -alkinyl or an imide of cyclic saturated or unsaturated carboxylic acids, whereat the C 1 -C 50 -alkyl or the cyclic substituent can be interrupted by one or multiple oxygen atoms, sulphur atoms, substituted and/or unsubstituted nitrogen atoms and/or by one or multiple groups of the type —C(O)O—, —OC(O)—, —C(O)—, —NHC(O)O—, —OC(O)NH— and/or —OC(O)O—, R 3 means Q 1 or a moiety of the formula R 6 —N—R 7 connected with a nitrogen atom to the triazine ring of the structure of the formula (I), R 1 , R 4 , R 5 , R 6 and R 7 are independently from each other H or Q 2 , and Q 2 means in each case a linear or branched C 1 -C 50 -alkyl, C 5 -C 20 -cycloalkyl, C 5 -C 20 -aryl, C 1 -C 20 -alkyl substituted C 5 -C 20 -aryl, C 2 -C 20 -heterocycle, C 2 -C 20 -alkenyl substituted C 2 -C 20 -heterocycle, C 1 -C 50 -alkyl substituted C 2 -C 20 -heterocycle, C 2 -C 20 -alkenyl, C 2 -C 20 -alkenyl substituted C 5 -C 20 -aryl or C 2 -C 12 -alkinyl, which in each case can be interrupted by one or multiple oxygen atoms, sulphur atoms, substituted and/or unsubstituted nitrogen atoms and/or by one or multiple groups of the type —C(O)O—, —OC(O)—, —C(O)—, —NHC(O)O—, —OC(O)NH— and/or —OC(O)O— and/or can have further functional groups like —OH, —NH 2 , —NHR 1 , SH, halogen, and (b) subsequent removal of excess of alcohol and water by simultaneously precuring at temperatures of 80-150° C. and pressures of 100-400 mbar, wherein the removal of excess alcohol and water as well as the simultaneous precuring occur in two thin film evaporators connected in series, wherein a first thin film evaporator is operated at 80 to 130° C. and the second thin film evaporator is operated in dependency from the throughput at 130 to 150° C., so that a solid resin is obtained and with said aminoplast resin having: a viscosity between 3 to 100 Pas at a temperature of 130° C. over a time period of at least 25 min, a glass transition temperature T G between 40° C. and 80° C., and a molar mass of M W =150-1000 g/mol.
