摘要： The present invention relates to a polyolefin composition comprising (A) a crosslinkable polyolefin with hydrolysable silane groups which upon hydrolysation form an acid or a base, characterised in that the acid or base generates a gel content of at least 40% after 40 hours in the 90°C cross-linking test, wherein the acid or base is added in an amount of 4.5 mmol/kg to an ethylene/vinyltrimethoxysilane copolymer with a MFR 2 = 2 g/10min, a density of 923 g/cm 3 , and 2 wt.% of vinyltrimethoxysilane and then is cross-linked in a waterbath at 90°C, and to a polyolefin composition comprising (i) a crosslinkable polyolefin with hydrolysable silane groups, and (ii) a non-polymeric compound with hydrolysable silane groups which upon hydrolysation form an acid or a base, characterised in that the acid or base generates a gel content of at least 40% after 40 hours in the 90°C cross-linking test, wherein the acid or base is added in an amount of 4.5 mmol/kg to an ethylene/vinyltrimethoxysilane copolymer with a MFR 2 = 2 g/10min, a density of 923 g/cm 3 , and 2 wt.% of vinyltrimethoxysilane and then is cross-linked in a waterbath at 90°C.
