    摘要： A filled polymer composition comprises (i) an ethylene/α-olefin interpolymer, and (ii) a filler. The ethylene/α-olefin interpolymer is a block copolymer having at least a hard block and at least a soft block. The soft block comprises a higher amount of comonomers than the hard block. The block interpolymer has a number of unique characteristics disclosed here. The filled polymer compositions provided herein, in certain embodiments, have relatively higher heat resistance and improved noise, vibration and harshness properties and can be used in automotive floorings, roofings, wire and cable coating applications.

    摘要： Disclosed in the present invention is a crosslinked polyethylene composition having improved processability comprises: 100 parts by weight of polyethylene, 0.03-5 parts by weight of crosslinking agent, 0.03-5 parts by weight of crosslinking promoter, and 0.01-1.5 parts by weight of free radical inhibitor, wherein the polyethylene is a copolymer and/or homopolymer containing at least 90 wt. % of vinyl and at least one C3-C8 α-alkenyl, and has a density in the range of 0.920-0.970 g/cm3, a melt index in the range of 2.5-17.5 g/10 min; the crosslinking agent is a peroxide crosslinking agent; the crosslinking promoter is an organic substance containing maleimido, (meth)acrylate group, and/or allyl, and/or a polymer containing more than 50% of vinyl; the free radical inhibitor is an organic antioxidant, a quinhydrone and/or a substituted quinhydrone. The crosslinked polyethylene composition of the present invention has a crosslinking efficiency index of more than 1,100 Nm/g and a δ torque value of more than 10 Nm at the temperature of 200° C., a significantly higher safety process temperature and a significantly improved crosslinking retardation time compared to the conventional crosslinked polyethylene composition, which make it especially be suitable for the production of rotational molding articles.
