Semiconductive polymer composition

A method of use of a semiconductive polymer composition comprising:

• (a) an ethylene C1-2-alkyl (meth)acrylate copolymer having an MFR2 of 4.5 g/10 min to 15 g/10 min and a C1-2-alkyl (meth)acrylate content of at least 9.0 wt %;
• based on the total weight of the ethylene C1-2-alkyl (meth)acrylate copolymer;
• (b) 36 to 48 wt % carbon black having an iodine adsorption number of 100 to 130 mg/g (ASTM D 1510-19a), an oil absorption number of 92 to 105 ml/100 g (ASTM D 2414-19) and an average primary particle size of 25 nm or less (ASTM D 3849-14aa);
• and
• (c) 0.05 to 2.0 wt % of at least one antioxidant, wherein the antioxidant is polymerized 2,2,4-trimethyl-1,2-dihydroquinoline;
• all weight percentages being based on the total weight of the semiconductive polymer composition unless mentioned otherwise;
• the method comprising using the semiconductive polymer composition to increase the smoothness of a semiconductive shield layer prepared using said composition.

A semiconductive polymer composition comprising:

• (a) an ethylene C1-2-alkyl (meth)acrylate copolymer having an MFR2 of 4.5 g/10 min to 15 g/10 min (ISO 1133, 2.16 kg. 190° C.) and a C1-2-alkyl (meth)acrylate content of at least 9.0 wt % based on the total weight of the ethylene C1-2-alkyl (meth)acrylate copolymer;
• (b) 36 to 48 wt % carbon black having an iodine adsorption number of 100 to 130 mg/g (ASTM D 1510-19a), an oil absorption number of 92 to 105 ml/100 g (ASTM D 2414-19) and an average primary particle size of 25 nm or less (ASTM D 3849-14aa);
• and
• (c) 0.05 to 2.0 wt % of at least one antioxidant, wherein the antioxidant is polymerized 2,2,4-trimethyl-1,2-dihydroquinoline;
• all weight percentages being based on the total weight of the semiconductive polymer composition, unless mentioned otherwise.
