摘要:
Formaldehyde-free aqueous binders containing: A) a polymer consisting of 5 to 100 wt% of an ethylenically unsaturated acid anhydride or an ethylenically unsaturated bicarboxylic acid, the carboxylic acid groups of which can form an anhydride group, and B) an alkanol amine with at least two hydroxyl groups.

摘要:
The invention relates to a textile two or three dimensional fabric made of fibers and/or strips and materials that are capable of swelling, wherein the respective amounts of fibers and/or strips and materials, that are capable of swelling, contained in said fabric are such that the fibers and/or strips are enveloped by the materials that are capable of swelling and the cavities of the fabric in a swollen state are partially or fully filled with material-bonded water and aqueous emulsions of (co) polymers of at least one ethylenically unsaturated monomer MON are applied as materials, that are capable of swelling, to the fibers and/or strips.
摘要:
The invention relates to a method for producing absorbent composite materials by bringing a support into contact with an emulsion containing at least one polymer material and at least one cross-linking agent and by curing the mixture on the support. The invention also relates to the absorbent composite materials and to their use in sealing materials for road construction, tunnel construction and hydraulic engineering and for excavations, flood control and the waterproofing of roofs.
