| titleOfInvention | Direct synthesis method for the production of etherified melamine resin condensates, melamine resin condensates, and use thereof |
| abstract | The invention relates to a direct synthesis method for producing etherified melamine resin condensates having average molar masses of 500 to 50,000. Said method is characterized by the fact that a) an etherified melamine resin precondensate is produced in an alcoholic solution in a first reaction step; b) the etherified melamine resin precondensate is concentrated in an alcoholic solution in at least one condensation step, C4 to C18 alcohols, diols of type HO-R-OH, and/or tetravalent alcohols that are based on erythritol being added to the melamine resin precondensate during and/or following the concentration process; c) the concentrated melamine resin precondensate is reacted by means of a mixer, especially a kneader, in a second reaction step. The inventive method allows melamine resin condensates having average molar masses of 500 to 50,000 to be produced, said melamine resin condensates being free of hydroxymethyleneamino groups that are bonded to the triazine rings and -NH-CH2-O-CH2-NH- groups which link the triazine rings. |
