Abstract
The invention relates to cocrystals of compounds of the formulae (I), (II) and (III), obtainable by reacting 1 mol of a succinic diester with 2 mol of a mixture of nitriles A-CN and B—CN, where A-CN and B—CN are present in the nitrile mixture in a molar ratio of 90:10 to 30:70 relative to one another, and where A-CN is 2-chlorobenzonitrile and B—CN is 4-X-benzonitrile where X=chlorine, methyl or nitrile.
Claims9
A mixed crystal comprising compounds of formula (I), (II) and (III),
- obtained by reacting 1 mol of a succinic diester with 2 mol of a mixture of nitriles A-CN and B—CN, in a molar ratio of 90:10 to 30:70 between the A-CN and B—CN in the mixture of nitriles, A-CN being 2-chlorobenzonitrile and B—CN being 4-X-benzonitrile where X=chlorine, methyl or nitrile.
The macromolecular material of natural or synthetic origin as claimed in claimed 7, wherein the macromolecular material of natural or synthetic origin is selected from the group consisting of plastics, resins, coatings, paints, printing inks, electrophotographic toners, electrophotographic developers, color filters and liquid inks.
