Catalytic deconstruction of waste polyethylene with ethylene to form propylene

Science, 2022
The conversion of polyolefins to monomers would create a valuable carbon feedstock from the largest fraction of waste plastic. However, breakdown of the main chains in these polymers requires the cleavage of carbon–carbon bonds that tend to resist ...

Coking-Resistant Polyethylene Upcycling Modulated by Zeolite Micropore Diffusion.

Journal of the American Chemical Society, 2022
Although the mass production of synthetic plastics has transformed human lives, it has resulted in waste accumulation on the earth. Here, we report a low-temperature conversion of polyethylene into olefins. By mixing the polyethylene feed with rationally

Polyethylene-polyethylene microfibrillar composites

Journal of Materials Science, 1993
Solid-state drawing of melt-crystallized, or gel(solution)-crystallized, polyethylene (PE) is well established as a means of producing high modulus high-strength fibres. Here, an alternative route, based on melt-processing, is reviewed and its merits are assessed.

Photoconduction of polyethylene

1967 Seventh Electrical Insulation Conference, 1966
Electronic conduction in various polymeric insulating materials has been discussed by many investigators.1–10 Since Fowler gave successful explanation to X-ray induced conductivity in plastics on the basis of energy-band theory including electron traps,1 electron traps have been considered to play an important role in electrical conduction, of polymer ...

Polyethylene/deutero-polyethylene phase behaviour

Polymer, 1985
Abstract A study of the phase behaviour of polyethylene/deuterated polyethylene (PEH/PED) has been carried out to address the question of phase segregation. The phase diagram has been determined by differential scanning calorimetry on carefully co-crystallized mixtures of PEH and PED that are of essentially the same molecular weight.

Electrical conduction in polyethylene terephthalate and polyethylene films [PDF]

Journal of Physics D: Applied Physics, 1971
Electrical conduction is studied in polyethylene terephthalate and to a limited extent in polyethylene over a range of fields up to 12×106 V cm−1. In common with previous investigations, it is found that the current decays with time according to an inverse power law, but this can be obviated by a conditioning procedure which then allows steady values ...
