Abstract

The present invention relates to a polyolefin resin composition with improved interfacial stability for insulation, a method for preparing the same and an article comprising the same, and more specifically, it relates to a polyolefin resin composition which comprises an ethylene-propylene block copolymer, a propylene-alpha-olefin rubber copolymer with a propylene content in a specific range, and polyethylene glycol with a number average molecular weight in a specific range, and has excellent flexibility, low-temperature impact resistance, heat resistance, etc., good insulation breakdown characteristics, and, in particular, excellent interface stability for long-term life improvement, so that it can be suitably utilized as an eco-friendly material for insulation layer in power cables for low-voltage, high-voltage, or extra-high-voltage direct current (DC) or alternating current (AC) transmission or distribution (especially, insulation layer of a high-voltage or extra-high-voltage power cables), a method for preparing the same and an article (especially, power cable) comprising the same.
