Hadi * , Ghazi Faisal Najmuldeen and Iqbal Ahmed Potential solvent for reconditioning polyolefin waste materials Abstract: Waste polymer reconditioning was examined by a method of dissolution/reprecipitation on low- and high-density polyethylene (PE) and polypropylene (PP). Toluene and petroleum ether, in different proportions, were used as solvents, and n-hexane was used as a non- solvent. Commercial polymer products used on an every- day basis were used with a virgin

Alfonso Grassi, Antonio Buonerba, and Sheila Ortega Sanchez 7 Bio-sourced polyolefins Abstract: In the last 5 years (2010–2015) the worldwide annual production of plastics surpassed the figure of 300 Mt; more than 80% of the plastic market deals with the production, transformation and end use of polyolefins. Plastics are a fundamental component of everyday life providing cost effective, light and disposable tools which find application in different fields. The increased concerns about the depletion of fossil reserves, the greenhouse gas emissions and

REACTIVE POLYOLEFIN ELASTOMER/POLYPROPYLENE BLENDS Zuning Li and Marianna Kontopoulou* Department of Chemical Engineering Queen's University Kingston, ON K7L 3N6, Canada ABSTRACT Reactive modification of polyolefin elastomer/polypropylene (PP) blends using an organic peroxide initiator is investigated. In the presence of a polyolefin elastomer matrix the crosslinking reaction dominates over the degradation of PP. Partition of the peroxide in the two phases and crosslink density depend highly on the method of incorporation of peroxide during

The synthesis and characterization of polyolefins continues to be one of the most important areas for academic and industrial polymer research. One consequence of the development of new "tailor-made" polyolefins is the need for new and improved analytical techniques for the analysis of polyolefins with respect to molar mass and chemical composition distribution. The present article briefly reviews different new and relevant techniques for polyolefin analysis. Crystallization analysis fractionation is a powerful new technique for the analysis of short-chain branching in linear low-density polyethylene (LLDPE) and the analysis of polyolefin blends and copolymers regarding chemical composition. For the fast analysis of the chemical composition distribution, a new high-temperature gradient high-performance liquid chromatography (HPLC) system has been developed. The efficiency of this system for the separation of various olefin copolymers is demonstrated. The correlation between molar mass and chemical composition can be accessed by on-line coupling of high-temperature size exclusion chromatography (HT-SEC) and 1H NMR spectroscopy. It is shown that the on-line NMR analysis of chromatographic fractions yields information on microstructure and tacticity in addition to molar mass and copolymer composition.
