Abstract
Abstract A polyadduct/polycondensate, which is water-dilutable when protonated with an acid, and which contains basic nitrogen groups, is obtained by polyaddition reaction of (A) Mannich bases obtained from monophenols and/or polyphenols, one or more secondary amines which contain one or more hydroxyalkyl groups, or a mixture of such a secondary amine with another secondary amine, and formaldehyde or a formaldehyde donor, with (B) an epoxy resin, the polyadduct/polycondensate of (A) and (B) containing groups, bonded to aromatic rings, of the formula (I) ##STR1## with or without groups of the general formula II ##STR2## where R 1 is a polydienyl radical, R 2 and R 3 are hydrogen or methyl and R 4 and R 5 are alkyl, hydroxyalkyl or alkoxyalkyl or are linked to one another to form a 5-membered or 6-membered ring. The polyadduct/polycondensate can be used, for example, as a surface-coating binder for the cathodic electrocoating of metal articles.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
186 words
A polyadduct/polycondensate which is water-dilutable when protonated with an acid and which contains basic nitrogen groups, the product being obtained by polyaddition reaction of (A) from 10 to 90% by weight of a Mannich base obtained from (a) monophenols and/or polyphenols, (b) one or more secondary amines which contain one or more hydroxyalkyl groups (b 1 ), or a mixture of such a secondary amine with another secondary amine (b 2 ) and (c) formaldehyde or a formaldehyde donor, with (B) from 10 to 90% by weight of one or more epoxy resins, wherein the polyadduct/polycondensate of (A) with (B) contains groups, bonded to aromatic rings, of the formula (I) ##STR18## with or without groups of the general formula II ##STR19## where R 1 is a polydienyl radical, R 2 and R 3 are identical or different and each is hydrogen or methyl and R 4 and R 5 are identical or different and each alkyl of 1 to 9 carbon atoms or hydroxyalkyl or alkoxyalkyl of 2 to 10 carbon atoms, or which are linked to one another to form a 5-membered or 6-membered ring.
Claim 2
Dependent Claim
186 words
A polyadduct/polycondensate which is water-dilutable when protonated with an acid and which contains basic nitrogen groups, the product being obtained by polyaddition reaction of (A) from 10 to 90% by weight of a Mannich base obtained from (a) monophenols and/or polyphenols, (b) one or more secondary amines which contain one or more hydroxyalkyl groups (b 1 ), or a mixture of such a secondary amine with another secondary amine (b 2 ) and (c) formaldehyde or a formaldehyde donor, with (B) from 10 to 90% by weight of one or more epoxy resins, wherein the polyadduct/polycondensate of (A) with (B) contains groups, bonded to aromatic rings, of the formula (I) ##STR18## with or without groups of the general formula II ##STR19## where R 1 is a polydienyl radical, R 2 and R 3 are identical or different and each is hydrogen or methyl and R 4 and R 5 are identical or different and each alkyl of 1 to 9 carbon atoms or hydroxyalkyl or alkoxyalkyl of 2 to 10 carbon atoms, or which are linked to one another to form a 5-membered or 6-membered ring.
Claim 3
Dependent Claim
36 words
A polyadduct/polycondensate as claimed in claim 1, wherein the component (b) used to prepare the Mannich base (A) is either (b 1 ) diethanolamine or a mixture of diethanolamine and another secondary amine (b 2 ).
Claim 4
Dependent Claim
86 words
A polyadduct/polycondensate as claimed in claim 1, wherein the monophenols or polyphenols, or mixtures of monophenols and polyphenols, used to prepare the Mannich base (A) are (a 1 ) one or more mononuclear or polynuclear monophenols and/or polyphenols, of which at least a proportion is replaced by (a 2 ) a mononuclear or polynuclear monophenol and/or polyphenol which contains groups of the general formula (I) ##STR20## with or without groups of the general formula (II) ##STR21## where R 1 to R 5 have the above meanings.
Claim 5
Dependent Claim
86 words
A polyadduct/polycondensate as claimed in claim 2, wherein the monophenols or polyphenols, or mixtures of monophenols and polyphenols, used to prepare the Mannich base (A) are (a 1 ) one or more mononuclear or polynuclear monophenols and/or polyphenols, of which at least a proportion is replaced by (a 2 ) a mononuclear or polynuclear monophenol and/or polyphenol which contains groups of the general formula (I) ##STR22## with or without groups of the general formula (II) ##STR23## where R 1 to R 5 have the above meanings.
Claim 6
Dependent Claim
33 words
A polyadduct/polycondensate as claimed in claim 1, wherein component (B) is prepared by reacting a polyepoxide compound with a less than equivalent amount of mononuclear or polynuclear monophenols and/or polyphenols (a 2 ).
Claim 7
Dependent Claim
33 words
A polyadduct/polycondensate as claimed in claim 2, wherein component (B) is prepared by reacting a polyepoxide compound with a less than equivalent amount of mononuclear or polynuclear monophenols and/or polyphenols (a 2 ).
Claim 8
Dependent Claim
