Claims
- 1. An electric component comprising an electric conductor insulated with electric insulation material having improved resistance to dielectric breakdown voltage by direct current, said electric composition comprising a styrenic resin composition which comprises 70 to 99.9% by weight of an (A) styrenic polymer having a high degree of syndiotactic configuration and 0.1 to 30% by weight of a (B) organic compound having a --NH-- group, a molecular weight of less than 10,000 and a thermal decomposition temperature of 270.degree. C. or higher.
- 2. The electric component according to claim 1 wherein said organic compound as the component (B) has an electron-attracting group adjacent to said --NH-- group.
- 3. The electric component according to claim 2 wherein said electron-attracting group contains a carbonyl group or an aromatic ring.
- 4. The electric component according to claim 1 wherein said composition comprises 80 to 99.9% by weight of said styrenic polymer as the component (A) and 0.1 to 20% by weight of said organic compound as the component (B).
- 5. The electric component according to claim 1 wherein said composition comprises 90 to 99.9% by weight of said styrenic polymer as the component (A) and 0.1 to 10% by weight of said organic compound as the component (B).
- 6. The electric component according to claim 1 wherein said organic compound as the component (B) is at least one compound selected from the group consisting of 2,4-bis(n-octylthio)-6-(4-hydroxy-3,5-di-tert-butylanilino)-1,3,5-triazine; N,N'-hexamethylenebis(3,5-di-tert-butyl-4-hydroxy-hydrocinnamide); N,N'-bis�3-(3,5-di-tert-butyl-hydroxyphenyl)propionyl!hydrazine; 2-phenoxypropionylhydrazide isophthalate; and N,N'-di-2-naphthyl-p-phenylenediamine.
- 7. The electric component according to claim 1 wherein the electric insulation material is in the form of a sheet of film.
- 8. The electric component according to claim 1 wherein the Dielectric Breakdown DC-voltage of the electric insulation material is 480 Kv/min or more in the form of a film.
- 9. The electric component according to claim 1, wherein said organic compound (B) is at least one compound selected from the group consisting of 2,4-bis(n-octylthio)-6-(4-hydroxy-3,5-di-tert-butylanilino)-1,3,5-triazine; N,N'-hexamethylenebis(3,5-di-tert-butyl-4-hydroxy-hydrocinnamide); N,N'-bis�3-(3,5-di-tert-butyl-hydroxyphenyl)propionyl!hydrazine; 3-(N-salicyloyl)amino-1,2,4-triazole; disalicyloylhydrazide decamethylenedicarboxylate; 2-phenoxypropionylhydrazide isophthalate; oxalyl-bis(benzylidene-hydrazide); N-formyl-N'-salicyloylhydrazine; N,N'-di-2-naphthyl-p-phenylenediamine; and 4,4'-bis(.alpha.,.alpha.'-dimethylbenzyl)diphenylamine.
- 10. The electric component according to claim 9 wherein the electric insulation material is in the form of a sheet of film.
- 11. The electric component according to claim 9 wherein the Dielectric Breakdown DC-voltage of the electric insulation material is 480 Kv/mm or more in the form of a film.
