  • Multimodal polyethylene copolymer resin composition, a preparation process therefor and a polymeric product comprising the same
    Patent number: 8889793
    Abstract: The invention relates to a multimodal polyethylene copolymer resin composition comprising (a) a lower molecular weight (LMW) ethylene polymer fraction and (b) a higher molecular weight (HMW) ethylene copolymer fraction, wherein the higher molecular weight (HMW) ethylene copolymer fraction comprises (b1) a higher molecular weight (HMW) ethylene copolymer subfraction having a weight average molecular weight at least 2 times the weight average molecular weight (Mw) of said multimodal polyethylene copolymer resin composition, which (b1) higher molecular weight (HMW) ethylene copolymer subfraction amounts from about 1-30 wt % of the total amount of the multimodal polyethylene copolymer resin composition and comprises comonomers in amount of at least about 1 wt % of the total amount of comonomer present in said multimodal polyethylene copolymer resin composition, a process for its preparation and its use.
