This study examines the preparation of several composites that are based on natural magnesium hydroxide (n-MDH) and various poly(ethylene-co-octene) polyolefin elastomers (POEs). Design experiment (DoE) principles have been applied in order to optimize mechanical, rheological, flame-retardant properties final composites. DoE allows one evaluate influence each variable an experiment’s properties...

By contrast to traditional free radical emulsion polymerization, catalytic polymerization allows for polymer microstructure control. In terms of monomers polymerizable, both techniques are largely complementary. Since the beginning of this decade, an increasing number of reports on polyolefin, polybutadiene, polyalkenamer, polynorbornene, polyketone and polyacetylene dispersions prepared by cat...

Polyolefin film products are in a state of continuous improvement in regard to their physical properties, aesthetic features, durability during processing, weatherability, and various types of special effects. Accordingly, the polymer producers of these film grade products, as well as the manufacturers of the downstream films are always interested in new developments in additive technology thes...

Plastic wastes, lube oils and coal-tar are evaluated, individually and combined, as additives to coal blends for the production of blast-furnace coke. The effects of adding 2 wt% of potential additives or their mixtures (50:50 w/w) on the coking capacity of coal, the pressure generated during the coking process and the coke quality parameters were evaluated. Using a combination of polyolefin wa...

This article gives a wide overview of different types mathematical models that can be used to describe the polymerization linear olefins with coordination catalysts. We expanded conventional classification into micro-, meso-, and mesoscale, include seven modelling levels: catalysis, kinetics, thermodynamic equilibrium, particle transport phenomena, interactions, reactor fluid dynamics, residenc...

This review considers the recent investigations in scope of biodegradability synthetic polymers, spanning polyethylene (PE), polypropylene (PP), and their corresponding composites, with a focus on influence oxo-additives (mostly transition metal salts). The types mechanisms oxidation acceleration are discussed. Furthermore, both physicochemical biological stages degradation is evaluated (labora...
