Polyethylene - Wikipedia
网页Metallocene polyethylene (PE-M) is prepared by means of metallocene catalysts, usually including copolymers (z. B. ethene / hexene). Metallocene polyethylene has a relatively narrow molecular weight distribution, exceptionally high toughness, excellent optical properties and a uniform comonomer content. Because of the narrow molecular weight ...
Fundamentals of Polyethylene – Part 5: Metallocenes
网页2020年1月1日 · Metallocene. In polypropylene, one of the four pendant groups is not a hydrogen atom. Instead it has been replaced by a multi-atom structure known as a methyl group (-CH 3). This group is bigger and bulkier than a hydrogen atom and it creates more space between the polymer chains.
Improved Properties of Metallocene Polyethylene…
网页2020年3月5日 · In this investigation, metallocene polyethylene (m-PE) was melt blended with poly (ethylene terephthalate) (PET) with an effort to achieve improved mechanical properties using a novel eccentric rotor extruder (ERE) …
Metallocene Polyethylene (mPE) - SABIC
网页SUPEER™ Metallocene LLDPE, COHERE™ polyolefin Plastomer and FORTIFY™ polyolefin Elastomer - for flexible film packaging and polymer modification solutions.
网页Phillips Chemical Company LLC’s Marlex® metallocene polyethylene products demonstrate outstanding optical properties compared to competitive metallocene linear low density polyethylene (mLLDPE) resins. In addition to their distinguished optical properties, Marlex® mLLDPE resins authenticate the impact and puncture
Structure–property relationships in metallocene polyethylenes
网页2002年9月15日 · The development of new polyolefins based on metallocene technologies represent a considerable advance in the performance of polyethylenes available for a wide range of applications. The ability to obtain a homogeneous short chain branching distribution and control molecular weight is remarkable.
Crystallization behavior and structure of metallocene polyethylene …
网页2022年3月19日 · Metallocene PE (mPE) has a narrow molecular weight distribution and improved mechanical and physical properties compared with conventional Ziegler–Natta PE. However, although its viscosity results in poor processing [1], introducing long-chain branches (LCBs) in the metallocene polymers is an effective approach for improving this shortcoming [2].
Improved Properties of Metallocene Polyethylene/Poly(ethylene ...
网页2020年3月5日 · In this investigation, metallocene polyethylene (m-PE) was melt blended with poly (ethylene terephthalate) (PET) with an effort to achieve improved mechanical properties using a novel eccentric rotor extruder (ERE) without the addition of any compatibilizers. The phase morphology, rheological properties, crystallization behavior, and …
Molecular Structure of Metallocene-Catalyzed Polyethylene ...
网页2002年2月28日 · The goal of this work was to provide a usable framework for describing the molecular structure of long-chain branched, metallocene-catalyzed polyethylene (mPE). This will allow better understanding of structure−property relations for these materials and in the future allow the development of new metallocene based systems with tailor-made ...
