Mixtures of water-soluble anionic (meth) acrylamide polymeric resins with natural resin adhesives for use as pulp adhesives in the manufacture of paper and paperboard, adhesives containing these mixtures and their use in paper

摘要

The present invention relates to mixtures of water-soluble synthetic anionic polymers consisting of at least 80%-wt acrylamide and/or methacrylamide and sizing media based on partly or totally saponified natural resins as well as the use of such mixtures in the production of paper and cardboard in order to reduce the absorbency and improve the dry strength of these products.
