Abstract

The invention relates to polymers obtained by S-alkylation of sulfinated polymers with alkylation agents, and AB-cross-linked polymers obtained by reacting polymers containing alkylation groups with low-molecular sulfinates, under S-alkylation, or AB-cross-linked polymers obtained by S-alkylation of sulfinated polymers with polymers containing alkylation groups.
