TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Process: The step of polymerizing or curing the composition containing (Ia) is carried out by heat, light or electron beams.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation: No preparation method is given. Preferred Components: (I) is an aryl diamine compound of formula (((D1)c1-Ar1-N(Ar2-(D1)c2)-((D1)c5)Ar5-(((D1)c3-Ar3)N-Ar4-(D1)c4))k) (II). (Ia) is an aryl diamine compound of formula (((D2)c1a-Ar1a-N(Ar2a-(D2)c2a)-((D2)c5a)Ar5a-(((D2)c3a-Ar3a)N-Ar4a-(D2)c4a))k1) (IIa).Ar1-Ar4, Ar1a-Ar4a = optionally substituted aryl;Ar5, Ar5a = aryl or arylene (both optionally substituted);c1-c5, c1a-c5a = 0-2 (where the sum of c1 to c5 and c1a to c5a is 1-8); andk, k1 = 0 or 1. Preferred Definitions:    D1 = substituted phenyl group of formula (IV); and    D2 = substituted phenyl group of formula (IVa); and    p, p1 = 0-4.    SPECIFIC COMPOUNDS - 61 Compounds (I) are disclosed e.g. (4-vinylphenyl)methyl 2-(4-(diphenylamino)phenyl)acetate of formula (IA), (3-vinylphenyl)methyl 2-(4-(diphenylamino)phenyl)acetate, (4-vinylphenyl)methyl 3-(4-(diphenylamino)phenyl)propanoate, (4-vinylphenyl)methyl 3-(4-(bis(3,4-dimethylphenyl)amino)phenyl)propanoate and (4-vinylphenyl)methyl 4-(4-(bis(3,4-dimethylphenyl)amino)phenyl)butanoate.    EXAMPLE - 3,4-Dimethylacetanilide (32.6 g), 4-iodobiphenyl (56 g), potassium carbonate (30.4 g), copper sulfate pentahydrate (1.5 g) and n-tridecane (50 ml) were added to a three-neck flask (500 ml). The mixture was stirred for 20 hours and heated at 220 degrees C under nitrogen flow. Then, the temperature was reduced to 120 degrees C, and then ethylene glycol (50 ml) and an aqueous potassium hydroxide solution (potassium hydroxide 15.7 g/water 20 ml) were added to the mixture. The obtained mixture was stirred for 6 hours. The temperature was reduced to room temperature, and toluene (200 ml) and water (150 ml) were added and the liquid was separated. A toluene layer was collected, and then, sodium sulfate (20 g) was added with stirring for 10 minutes, and then the sodium sulfate was filtered to obtain (4-vinylphenyl)methyl 3-(4-((3,4-dimethylphenyl)-(4-phenylphenyl)amino)phenyl)propanoate (42.1 g).
