摘要:
The invention relates to a method for producing a polymer using a chain transfer agents. In particular, the invention relates to a process for polymerizing a polymer in the presence of a mixture of at least two chain transfer agents, which mixture comprises a polar chain transfer agent (polar CTA), and a non-polar (non-polar CTA).
摘要:
The invention relates to a use of a polymer composition for producing an insulation layer of an AC power cable with and to an AC cable surrounded by at least an insulating layer comprising said polymer composition.
摘要:
A polymer composition with improved DC electrical properties, a method for producing the polymer composition, and a cable surrounded by at least one layer comprising the polymer composition are provided.
摘要:
A crosslinkable and crosslinked polymer composition with improved DC electrical properties and a cable surrounded by at least one layer comprising the polymer composition are provided.
摘要:
The invention relates to a semiconductive polymer composition for use in power cables. The composition comprises a multimodal ethylene homo- or copolymer produced in a polymerization process comprising a single site catalyst whereby the polymer composition has a density of 870 to 930 kg/m3, a MFR2 of 1 to 30 g/10 min and a Mw/Mn of less than or equal to 10.
