Installing a Trigger to Upcycle High-Density Polyethylene. [PDF]

J Am Chem Soc
Creating C═C bonds as "weak" sites in the stable C-C chains of polyethylene (PE) is an appealing strategy to promote sustainable development of the polyolefin industry. Compared to methods, such as dehydrogenation and postpolymerization modification, the copolymerization of ethylene (E) and butadiene (BD) should be a convenient and direct approach to ...

Reinforcing high-density polyethylene by phenolic spheres

MATEC Web of Conferences, 2018
Phenolic spheres are synthesized through resorcinol and formaldehyde. The phenolic spheres were blended with HDPE to prepare binary composites. The rheological properties and mechanical properties of the composites were studied.

Biodegradable High‐Density Polyethylene‐like Material

Angewandte Chemie, 2022
AbstractWe report a novel polyester material generated from readily available biobased 1,18‐octadecanedicarboxylic acid and ethylene glycol possesses a polyethylene‐like solid‐state structure and also tensile properties similar to high density polyethylene (HDPE).

Microbial degradation of virgin polyethylene by bacteria isolated from a landfill site

SN Applied Sciences, 2022
In this study we evaluate the extent of degradation of high-density polyethylene by bacterial isolates obtained from landfill. The microorganisms are isolated from plastic wastes deposited in the landfill for 2–3 years and 17 years.
