摘要：<p>Modified polyethyleheimine (I) used as polyelectrolyte for addn. to paper pulp is modified with acrylamide and acrylic acid. (I) contains 10-50 mole-% ethylene-amino-beta-amide (II) and 10- 50 mole-% ethyleneamino-propionate (III) units. Pref. (I) is also modified with guanidine and contains 10-50 mole-% quanidine units. The addn. of (I) ensures a high degree of dewatering and filler retention in a wide pH range, high degree of whiteness of the paper produced and reduced biological growth and slime formation.</p>
