It has been found that when a mixture of TAIC (hereinafter referred to as TAIC), a specific oxidative deterioration inhibitor, etc. is added to polyethylene as a base polymer, the occurrence of water trees can be effectively suppressed.
本発明は、このような事実に基づいてなされたものであ

This is because if it is less than 1.0 parts by weight, the desired degree of crosslinking cannot be obtained, and if it exceeds 3.0 parts by weight, scorch will occur.

剤の混合合計量は、0.10〜0.40重量部とする。The total amount of these phenol-based and amine-based oxidation inhibitors mixed is 0.10 to 0.40 parts by weight.

とする。This is because if it is less than 0.10 parts by weight, the heat aging properties will be poor.
This is because sufficient improvement cannot be achieved, and if the amount exceeds 0.40 parts by weight, the degree of crosslinking will decrease. Furthermore, the blending ratio of these phenol-based and amine-based oxidative deterioration inhibitors themselves shall be varied depending on the amount of DCP added.

越えると偏肉や垂れ落ちが生じるからである。Further, the polyethylene used in the present invention is not particularly limited, but low density polyethylene is preferable, and
Furthermore, the terminal carbon-carbon double bond is 0.7 to 1 per 1000 carbon atoms. 5 pieces, melt flow ratio (M,
F, R,) is preferably 0.5 to 4°0. This is because if the number of terminal carbon-carbon double bonds is less than 0.7, the degree of crosslinking is low, and if this number exceeds 1.5, scorch is likely to occur. Further, if the melt flow ratio is less than 0.5, scorch is likely to occur, and if it exceeds 4.0, uneven thickness or dripping will occur.
