Abstract
The present invention relates to a water-soluble binder composition comprising at least one carbohydrate component and at least one carbon dioxide reaction product comprising at least the reaction product(s) of carbon dioxide with at least one nitrogen-containing compound. It further relates to a method of its manufacture, its use, a method of manufacturing a collection of matter bound by said polymeric binder, as well as a binder solution or dispersion comprising said binder composition.

-18. (canceled)
A method of manufacturing a collection of matter bound by a polymeric binder comprising the steps:
- (i) providing a collection of matter,
- (ii) providing a water-soluble, curable, thermosetting binder composition, comprising:
- at least one carbohydrate component wherein the at least one carbohydrate component comprises a reducing sugar and/or a component which yields a reducing sugar in situ, and
- at least one carbon dioxide reaction product comprising at least the reaction product(s) of carbon dioxide with at least one nitrogen-containing component wherein the at least one nitrogen-containing component comprises an organic amine comprising at least one primary amine group as well as salts thereof,
- in a solvent to obtain a solution or dispersion,
- (iii) applying the solution or dispersion obtained in step (ii) to the collection of matter, and
- (iv) applying energy to the collection of matter containing said solution or dispersion to cure the binder composition.
A method of manufacturing a collection of matter bound by a polymeric binder comprising the steps:
- (i) providing a collection of matter,
- (ii) providing a water-soluble, curable, thermosetting binder composition, in a solvent to obtain a solution or dispersion, wherein the binder composition is obtained by a method comprising the steps of:
- (a) providing at least one carbohydrate component wherein the at least one carbohydrate component comprises a reducing sugar and/or a component which yields a reducing sugar in situ,
- (b) providing at least one nitrogen-containing component wherein the at least one nitrogen-containing component comprises an organic amine comprising at least one primary amine group as well as salts thereof,
- (c) providing carbon dioxide,
- (d) mixing in a solvent the carbohydrate component(s) and the nitrogen-containing component(s), and optionally cooling at room temperature, and
- (e) bubbling carbon dioxide into the mixture obtained in step (d);
- or
- (a′) providing at least one carbohydrate component wherein the at least one carbohydrate component comprises a reducing sugar and/or a component which yields a reducing sugar in situ,
- (b′) providing at least one nitrogen-containing component wherein the at least one nitrogen-containing component comprises an organic amine comprising at least one primary amine group as well as salts thereof,
- (c′) providing carbon dioxide,
- (d′) reacting the carbon dioxide with the nitrogen-containing component, and
- (e′) mixing in a solvent the carbohydrate component(s) and the reaction product of (d′),
- (iii) applying the solution or dispersion obtained in step (ii) to the collection of matter, and
- (iv) applying energy to the collection of matter containing said solution or dispersion to cure the binder composition.
