【表】DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composition comprising a 4-methylpentene-1 polymer (hereinafter referred to as PMP) mixed with a small amount of carbon black. A small amount of carbon black is added to PMP in order to color it black and improve its reinforcing properties and weather resistance, but according to the research of the present inventor, the metal components contained as impurities in carbon black
On the other hand, if the content of metal components derived from carbon black in PMP is below a certain limit, the originally excellent heat resistance of PMP will not be significantly impaired. The present invention proposes a PMP composition as described in the claims, which was developed based on the above new findings. As PMP, homopolymers and copolymers of 4-methylpentene-1 are used. Examples of such polymers include ASTM D 1238-70 (260
Melt index measured at ℃, 5Kg) is 1~
100, especially 5 to 80, and the density at 23℃ is 0.82 to
It is a crystalline polymer with stereoregularity of about 0.85. PMP is produced by a method such as polymerizing 4-methylpentene-1 alone or together with a copolymerization component described below using a Ziegler type catalyst. Copolymerization components include ethylene, propylene, butene, pentene, hexene, octene,
-Methyl-butene-1,3-methyl-pentene-
Linear or branched aliphatic hydrocarbon vinyl compounds having about 2 to 25 carbon atoms such as 1,4,4'-dimethyl-pentene-1,3-methyl-hexene-1, styrene, orthodivinylbenzene, metadivinylbenzene Examples include aromatic hydrocarbon vinyl compounds having about 8 to 25 carbon atoms, such as paradivinylbenzene, metadivinyltoluene, paradivinyltoluene, and α-methylstyrene. One type of copolymerization component may be used, or two or more types may be used. The PMP used in the present invention preferably contains at least 60% by weight of 4-methylpentene-1 component. Aromatic hydrocarbon vinyl compound components
One of the preferable PMPs is one containing 0.1 to 20% by weight. Carbon blacks include acetylene black, furnace black, channel black,
Rubbers such as thermal black, buttock black, lamp black, etc., which are used in the plastics industry for imparting conductivity, reinforcing properties, or coloring, can be used. However, the amount of carbon black blended into PMP is such that the ash content in the composition consisting of PMP and carbon black is less than 0.003% by weight.
Preferably it is limited to an amount range of less than 0.002% by weight. Use the maximum amount of carbon black available.
The ash content may be determined by calculation from the individual ash contents of PMP and carbon black, or the ash content of a composition consisting of PMP and carbon black may be determined by actual measurement. The ash content of the composition of the present invention, PMP or carbon black is
May be measured according to ASTM D 1506-59. In the present invention, isophthalic acid bis(2-phenoxypropionyl hydrazide), 3-(N-salicyloyl)amino-1,2,
Known metal deactivators such as 4-triazole and oxalic acid bis(benzylidene hydrazide) are added in amounts ranging from 0.1 to 100 parts by weight of PMP.
Heat resistance is further improved when used in combination at about 1.0 part by weight. Hereinafter, the present invention will be explained in more detail with reference to Examples and Comparative Examples. The compositions of Examples and Comparative Examples shown in the table below were mixed in an extruder at 250°C to produce pellets of about 3 mm square using a pelletizer. The obtained pellets were extruded to a thickness of 0.4 mm using an extruder with a diameter of 65 mm and L/D = 22 at a die temperature of 300°C onto a stranded conductor (preheated to 150°C) consisting of 7 tin-plated copper wires with an outer diameter of 0.32 mm. An insulated wire was manufactured. Each insulated wire was heated to 180℃ and the dielectric breakdown strength changed over time.
The number of days at which 50% is reached is shown as the lifespan in the same table. 【table】
