A polymer composition comprising i) an ethylene polymer (a) with a polar comonomer (s), wherein - the polar comonomer is present in the ethylene polymer (a) in an amount of 4 , 5 to 18% by mole, when measured according to "comonomer contents" as described above in "Determination methods", and - the polar comonomer is selected from the group of unsaturated carboxylic acid esters, and wherein - the ethylene polymer (a) optionally carries units containing functional group (s) different from said polar comonomer, and ii) units (b) containing silane group (s), wherein the polymer composition has - the Refractive Index difference of the polymer composition within the temperature range of 10 to 70 ° C is less than 0.0340, when measured according to "Refractive Index" measurement as described in the specification at "Methods of Determination"; and A Shear Refinement Index, SHI0.05 / 300, of 10.0 to 35.0 when measured in accordance with "Rheological Properties: Dynamic Shear Measurements (frequency oscillation measurements)" as described herein. descriptive in "Determination Methods". |
