摘要:
An aqueous acidic polymerization liquid comprising polymerizable monomers or oligomers with carboxylate and/or carboxylic acid moiety or moieties, and edge modified clay that is homogenously dispersable in said liquid is provided, and also methods for making such liquids, and also edge-modified-clay linked water-absorbing polymers made by with said liquids and methods, and disposable absorbent articles comprising such edge-modified-clay linked water-absorbing polycarboxylate/polycarboxylic acid polymers.
摘要:
The invention relates to the provision of two novel crystalline forms I and II for 5-amino-2,3-dihydrophthalazine-1,4-dione sodium salt. Surprisingly, it was discovered that form I and form II have differing immunological effects. This advantageous property is useful for immunospecific applications. In addition, both forms have advantageous physicochemical properties, which are useful in the production, further processing and/or use of a pharmaceutical preparation of form I or form II or a mixture of both.
