    Description

    EXAMPLES

    [0226] In the case of molecularly inhomogeneous substances, the stated molecular weights hereinafter as already in the above descriptionare number-average values. The molecular weights or number-average molecular weights M.sub.n, in the event that titratable hydroxyl or amino groups are present, are determined by end group determination via the finding of the OH number, the amine number or the NCO number.

    [0227] Unless stated otherwise, figures in parts are parts by weight and figures in percent s are percent by weight.

    [0228] Solids Content

    [0229] The sample (2.00.1 g of test substance) is weighed into an aluminum dish that has been dried beforehand and dried in a drying cabinet at 150 C. for 10 minutes, cooled down in a desiccator, and then re-weighed. The residue corresponds to the solids content.

    [0230] NCO Number

    [0231] The free NCO content of the polyisocyanates being used and the course of reaction of the NCO additions is determined according to EN ISO 9369 by reaction with butylamine and subsequent titration of the excess of amine. These methods are also described in Saul Patai The Chemistry of Cyanates and their Thioderivates, Part 1, Chapter 5, 1977.

    [0232] OH Number

    [0233] The OH number is determined according to DIN ISO 4629 by acetylation with an excess of acetic anhydride. Subsequently, the excess acetic anhydride is hydrolyzed to acetic acid by addition of water and back-titrated with ethanolic KOH solution. The OH number indicates the amount of KOH in mg equivalent to the amount of acetic acid bound in the acetylation of 1 g of substance.

    [0234] Amine Number

    [0235] The amine number (AN) is understood to mean the amount of KOH in mg corresponding to the amine content of 1 g of substance. The amine number is determined according to DIN 16945 by potentiometric titration with 0.1 N perchioric acid in acetic acid.

    [0259] General Method for Preparation of the Amido Amines AA of the General Formula (IV)

    [0260] First Step (Michael addition) to give Intermediate I (Table 2)

    [0261] A four-neck flask provided with a stirrer, thermometer, water separator and nitrogen inlet tube is initially charged with y g of the amine B and/or z g of the amino alcohol C at room temperature. Subsequently, x g of component A are added gradually, such that the reaction temperature does not exceed 35-40 C. The progress of the reaction is monitored by means of 1H NMR. The reaction is considered to have ended when the CC double bond of the ethylenically unsaturated ester compound A has been fully converted.

    [0262] Second Step (amidation) to give Amido Amine AA (Table 3)

    [0263] On completion of conversion of the CC double bond of the ethylenically unsaturated ester compound A in the first step, the ester group of the intermediate I obtained is amidated with a primary or secondary amino group of an amine component B and/or

    [0264] C, by heating the Michael adduct to 80 C. and adding the amine B and/or C to the reaction mixture at 80 C. and then increasing the temperature stepwise to 120 C. For better removal of the alcohol formed from the reaction mixture, a reduced pressure of 500 mbar is applied after one hour of reaction time at 120 C. The reaction mixture is stirred under these conditions until monitoring of the reaction by infrared spectroscopy shows complete conversion of the ester groups to amide groups. Dilution with PMA is optionally possible after the reaction.

The progress of the reaction is followed by means of titrimetric determination of the NCO number to EN ISO 9369. The reaction is considered to have ended when an NCO content of <0.1% is determined. Dilution with PMA is optionally possible during or after the reaction.

    [0271] In a Stage Sequence ii-b) (Table 5)

    [0272] First Step

    [0273] A four-neck flask equipped with a stirrer, thermometer, dropping funnel, reflux condenser and nitrogen inlet tube is initially charged with y g of the intermediate I and heated to 70 C. while stirring under nitrogen. Subsequently, x g of monoadduct M are added gradually, such that the reaction temperature does not exceed 80 C. Subsequently, the reaction mixture is stirred at 80 C. until the isocyanate has reacted to completion. The progress of the reaction is followed by means of titrimetric determination of the NCO number to EN ISO 9369. The reaction is considered to have ended when an NCO content of <0.1% is determined.

    [0274] Second Step

    [0275] On completion of reaction of the isocyanate group with an alcohol group, a primary amino group or a secondary amino group of an intermediate I in the first step, the intermediate J obtained is amidated with a primary or secondary amino group of an amine component B and/or C, by adding the amine B and/or C to the reaction mixture at 80 C. and increasing the temperature stepwise to 120 C. For better removal of the alcohol formed from the reaction mixture, a reduced pressure of 500 mbar is applied after one hour of reaction time at 120 C. The reaction mixture is stirred under these conditions until monitoring of the reaction by infrared spectroscopy shows complete conversion of the ester group to the amide group. In the case of products containing polyester in the Y radical, such that it becomes more difficult to monitor the reaction by infrared spectroscopy, the end of the reaction is s determined in that no further alcohol forms; thus, the amidation is considered to have ended. Dilution with PMA is optionally possible after the reaction.
