A modified polylysine comprising a polylysine obtained in any way which has been reacted with at least one further compound selected from the group consisting of compounds comprising acid groups, compounds comprising isocyanate groups, compounds comprising keto groups, compounds comprising aldehyde groups, compounds comprising activated double bonds, alkylene oxides, polyalkylene oxides which are terminated with amino groups or acid groups and have a functionality of one, two or more, lactones, lactams, alkylating reagents, saturated or unsaturated long-chain carboxylic acids, amino-reactive derivatives of saturated or unsaturated long-chain carboxylic acids, aliphatic or aromatic isocyanates, trialkylsilyl halides, perfluoroalkyl halides, and perfluoroalkylcarboxylic acid.
A modified polylysine comprising a high-functionality highly branched polylysine produced by the process of reacting
- (A) a salt of lysine with at least one acid,
- (B) optionally, at least one amino acid other than lysine,
- (C) optionally, at least one dicarboxylic or polycarboxylic acid or copolymerizable derivatives thereof, and
- (D) optionally, at least one diamine, polyamine or copolymerizable derivatives thereof
- with one another in the presence of at least one catalyst, wherein said polylysine has a weight-average molecular weight Mw of more than 10 000 Da and a gel content of not more than 20%,
- wherein said high-functionality highly branched polylysine has been reacted with at least one further compound selected from the group consisting of compounds comprising acid groups, compounds comprising isocyanate groups, compounds comprising keto groups, compounds comprising aldehyde groups, compounds comprising activated double bonds, alkylene oxides, polyalkylene oxides which are terminated with amino groups or acid groups and have a functionality of one, two or more, lactones, lactams, alkylating reagents, saturated or unsaturated long-chain carboxylic acids, amino-reactive derivatives of saturated or unsaturated long-chain carboxylic acids, aliphatic or aromatic isocyanates, trialkylsilyl halides, perfluoroalkyl halides, and perfluoroalkylcarboxylic acid.
A method of using a high-functionality highly branched polylysine produced by the process of reacting
- (A) a salt of lysine with at least one acid,
- (B) optionally, at least one amino acid other than lysine,
- (C) optionally, at least one dicarboxylic or polycarboxylic acid or copolymerizable derivatives thereof, and
- (D) optionally, at least one diamine, polyamine or copolymerizable derivatives thereof
- with one another in the presence of at least one catalyst, wherein said polylysine has a weight-average molecular weight Mw of more than 10 000 Da and a gel content of not more than 20%
- as an adhesion promoter or thioxotropic agent, solubilizer, phase transfer reagent for water-insoluble chemicals, phase transfer reagent for water-soluble chemicals, surface modifier or component in the production of printing inks, paints, coatings, adhesives, sealants, corrosion control products, casting elastomers or foams.
A method of using a non-crosslinked hyperbranched polylysine produced by the process of reacting
- (A) a salt of lysine with at least one acid,
- (B) optionally, at least one amino acid other than lysine,
- (C) optionally, at least one dicarboxylic or polycarboxylic acid or copolymerizable derivatives thereof, and
- (D) optionally, at least one diamine or polyamine or copolymerizable derivatives thereof
- with one another in the presence of at least one catalyst, wherein the reaction is carried out at less than 180° C., wherein said polylysine has a gel content of not more than 20%,
- as an adhesion promoter or thioxotropic agent, solubilizer, phase transfer reagent for water-insoluble chemicals, phase transfer reagent for water-soluble chemicals, surface modifier or component in the production of printing inks, paints, coatings, adhesives, sealants, corrosion control products, casting elastomers or foams.
