Abstract:
A polyurea constructed from:a) a diamine which contains a group â€”(â€”CH2CH2Oâ€”)nâ€”(C3H6â€”Oâ€”)m, where the order of the alkylene oxide units is arbitrary and m and n independently of one another are an integer between 0 and 50, and m+n is between 5 and 60, and b) at least one polysiloxane of the formula II â€ƒin which the order of the siloxane units is arbitrary â€ƒd is from 5 to 200, â€ƒe is from 1 to 20, â€ƒZ is a radical of the formula â€”(CH2)fâ€”NH2 in which f is a number from 1 to 10, or â€ƒZ is a radical of the formula â€”(CH2)gâ€”NHâ€”(CH2)hâ€”NH2 in which g and h independently of one another are from 0 to 6. or â€ƒZ is (CH2)fâ€”(CH2â€”CH2O)nâ€”(C3H6O)mâ€”H, in which n+m is from 5 to 60 , and m and n independently of one another are from 0 to 50, and c) at least one diisocyanate, and d) optionally a di-, tri- or tetraamine or polyamine which contains at least one ionogenic group, and e) optionally one or more diamines having a molecular weight of from 60 to 6000 g/mol, where the polyurea contains at least one ionogenic or ionic group.
