1967), "Advances in the chemistry of carbodiimides
," Chemical Reviews, 2:107-152.
GSI Exim is exhibiting some of its latest materials, such as Nobel Waterborne Carbodiimides
(Carbolites[R]), fluorochemical-based products, chrolinated polyethylene, and some specialty additives.
If a polyester must be used in a wet environment, carbodiimides
help in prolonging their longevity.
The most common crosslinkers are isocyanates, aziridines, and carbodiimides
To overcome problems associated with reagent toxicity of the GA, carbodiimides
have been used to cross-link collagen.
Various organic substances, such as diepoxides, diisocyanates, dianhydrides, carbodiimides
, and bisoxazolines, have been used to extend PET chains [8, 9, 22].
1-10) A number of crosslinkers have been employed for latex coatings, including amino resins, isocyanates, carbodiimides
, aziridines, oxazolines, and aromatic epoxides.
The addition of carbodiimides
to polyester millable urethanes greatly improves the hydrolysis resistance at room temperature and elevated temperatures.
(diimides derived from carbon dioxide) are used extensively in the formation of peptide amide bonds from carboxylic acids and amines.
The Polyurethane/Plastics Division of Rhein Chemic Rheinau GmbH in Mannheim-Rheinau, Germany, has developed the Stabaxol range of carbodiimides
for use as hydrolysis stabilizers in adhesives, where they improve performance and lengthen service life.
6,184,410 B1: Researchers for BASF AG, Ludwigshafen, Germany, have earned a patent for the process of preparing carbodiimides
based on 1,3-bis (1-methyl-l-isocyanatoethyl) benzene.
Furthermore, greater than 90 per cent ee was obtained for products of the Pd-catalyzed cycloaddition of aziridines and symmetrical or unsymmetrical carbodiimides
, using BINAP as the chiral ligand.
