摘要：
The present invention relates to new water-soluble polyquaternary compounds which are obtained by imidation of (A) specific alternating copolymers of maleic anhydride and olefines with (B) specific amines and (C) subsequent alkylation of the reaction product AB, the components (A) and (B) having the meaning given in the text of the Application. The invention furthermore relates to a process for the preparation of these water-soluble polyammonium compounds and their use as agents for improving the wet and dry tear strength of paper. The invention also relates to new intermediate products for the preparation of the compounds according to the invention.
