1. A METHOD FOR MANUFACTURING ELECTRIC WIRES INSULATED WITH A FOAM POLYOLEFIN RESIN BY CONTINUOUS, STALE EXTRUSION WHEREIN A FOAMAABLE POLYOLEFIN RESIN COMPOSITION IS PREPARED BY MIXING A POLYOLEFIN RESIN WITH A FOAMING AGENT COMPRISING AZODICARBONAMIDE AND BETWEN ABOUT 10 AND 150 PERCENT BY WEIGHT OF AT LEAST ONE MATERIAL HAVING A SOLUBILITY PARAMETER OF AT LEAST 12.0 BASED ON THE AMOUNT OF SAID AZODICARBONAMIDE AND EXTRUDING IT ON AN ELECTRIC CONDUCTOR UNDER CONDITIONS IN WHICH SAID AZODICARBONAMIDE DECOMPOSES, SAID MATERIAL HAVING SAID SOLUBILITY PARAMETER BEING SELECTED FROM THE GROUP CONSISTING OF POLYHYDRIC ALCOHOLS HAVING LESS THAN EIGHT CARBON AOMS, ETHANOL AMINES HAVING LESS THAN SIX CARBON ATOMS, ALKANOLS HAVING LESS THAN THREE CARBON AOMS, DIMETHYL SULFOXIDE, CARBOXYMETHYL CELLULOSE, METHYL CELLULOSE, LIGNIN, LIGNIN SULFONIC ACID, LACTONES, ALKYL ACETAMIDES, ALKYLFORMAMIDES, PHENOLS, ETHYLENE CARBONATE, THIOUREA, SUCCINIMIDE, AND COMPOUNDS CONTAINING A 1,3,5-TRIAZINE RING EXPRESSED BY THE GENERAL FORMULA
2. A method according to claim 1 wherein the foamable polyolefin-series resin composition is extruded on an electric conductor in a thickness of less than 1.0 mm.
3. A method according to claim 1 wherein 10 to 150 per cent by weight of the material having a solubility parameter of 12.0 or more is added based on the amount of azodicarbonamide used.
4. A method according to claim 1 wherein the polyolefin-series resin is a homopolymer of olefins.
5. A method according to claim 1 wherein the polyolefin-series resin is a copolymer of olefins and vinyl monomers.
6. A method according to claim 1 wherein the polyolefin-series resin is polyethylene.
7. A method according to claim 1 wherein the polyolefin-series resin is polypropylene.
8. A method according to claim 1 wherein the foaming agent consists of azodicarbonamide alone.
9. A method according to claim 1 wherein the foaming agent consists of azodicarbonamide and another foaming agent thermally decomposable at the extrusion temperature of the foamable polyolefin-series resin composition.
10. A method according to claim 1 wherein the foaming agent consists of azodicarbonamide and a volatile liquid foaming agent that turns into gas at the extrusion temperature of the foamable polyolefin-series resin composition.
11. A method according to claim 1 wherein the foaming agent consists of azodicarbonamide and at least one gas.
12. A method according to claim 9 wherein the thermally decomposable foaming agent is at least one selected from the group consisting of p,p''-oxybisbenzenesulfonyl hydrazide, p-toluenesulfonyl semicarbazide, and dinitrosopentamethylene tetramine.
13. A method according to claim 10 wherein the volatile liquid foaming agent is at least one selected from the group consisting of benzene, hexane, isopentane, n-pentane, petroleum ether and monofluorotrichloromethane.
14. A method according to clam 11 wherein the gas used As a foaming agent is at least one selected from the group consisting of carbon dioxide gas, nitrogen gas, propane, butane and dichlorodifluoromethane.
15. A method according to claim 1 wherein the material having a solubility parameter of 12.0 or more is at least one selected from the group consisting of sodium salt of carboxymethyl cellulose, lignin, and melamine.
16. A method according to claim 1 wherein the material having a solubility parameter of 12.0 or more is at least one selected from the group consisting of ethylene glycol, glycerin and triethanolamine.
