| titleOfInvention | Homogeneous poly (alkylene) guanidine and method for producing the same |
| abstract | The present invention provides a) an alkylenediamine of the formula NH 2 — (CH 2 ) m —NH 2 (where m = 4 to 12, especially 6 to 10) in a reaction vessel, and the alkylenediamine is used as the result. Is heated to a temperature equal to or higher than the melting point of the alkylenediamine, typically 25 ° C to 115 ° C (preferably 55 ° C to 110 ° C). Step b) adding guanidine salt, especially guanidine hydrochloride little by little, and reacting with alkylenediamine until formation of alkylene (guanidine) monomer is completed, and c) formation of poly (alkylene) guanidine Up to at least the monomer formed in step b) is reacted at a minimum temperature at which the polymerization to the desired poly (alkylene) guanidine is initiated. Of poly (alkylene) guanidine, wherein steps a) and b) for forming the alkylene (guanidine) monomer are carried out at a temperature below the minimum polymerization temperature and all steps are carried out with stirring. It relates to a manufacturing method. A further aspect of the invention is to provide at least 85% by weight of the desired linear poly (alkylene) guanidine having 3-14, preferably 4-10, alkylene monomer units in the molecule as the main product. , In particular at least 90% or 97%, by-products, in particular branched isomers of poly (alkylene) guanidines, at a content of at most 15%, 10%, 5% or 3%. , A homogeneous poly (alkylene) guanidine obtainable by the method described above.
