Abstract:
Bi-component superabsorbent materials are disclosed. The superabsorbent materials comprise a mixture of about 20% to about 40%, by weight, poly-(vinylamine) polymer or other basic resin and about 60% to about 80%, by weight of an acidic water-absorbing polymer, like polyacrylic acid.
Abstract:
The novel photo-cross-linkable polymers are suitable as coating materials. The photo-cross-linkable polymers contain a biphenylene unit, which can be dimerized by exposure. Attached to the biphenyl unit are side chains of a polymer with a high temperature resistance and a high chemical stability. Through exposure, the biphenylene units dimerize, whereby the polymers are spatially cross-linked.
Abstract:
The present invention is directed to alkanal derivatives of water-soluble polymers such as poly(ethylene glycol), their corresponding hydrates and acetals, and to methods for preparing and using such polymer alkanals. The polymer alkanals of the invention are prepared in high purity and exhibit storage stability.
