High Density Polyethylenes Bearing Isolated In-Chain Carbonyls [PDF]

Angewandte Chemie - International Edition, 2021
Abstract Polyethylene materials are highly important polymers which are produced in the largest volume among all plastics. Due to the chemical inert property of saturated carbon-carbon bonds, the degradation of polyethylene is extremely challenging, which prevents them from efficient chemical recycling.

Rheological properties of high-density polyethylene/linear low-density polyethylene and high-density polyethylene/low-density polyethylene blends

Polymer Bulletin, 2021
In this work, the effect of the linear low-density polyethylene (LLDPE) containing 1-butene or 1-hexene α-olefin short-chain branching (SCB) and low-density polyethylene (LDPE) containing long-chain branching (LCB) on the rheological properties of high-density polyethylene (HDPE)/LLDPE and HDPE/LDPE blends was investigated.

Processability‐enhanced bimodal high‐density polyethylene with comb‐branched high‐density polyethylene

Journal of Applied Polymer Science, 2017
ABSTRACTTwo solution reactors in series were utilized to synthesize comb‐branched high‐density polyethylene (HDPE), cbHDPE, where the first reactor prepares vinyl‐terminated HDPE macromers catalyzed by an organometallic catalyst favoring beta hydride transfer and the second reactor copolymerizes HDPE macromers with ethylene using a different ...

Necking of high‐density polyethylene

Journal of Applied Polymer Science, 1971
AbstractNecking draw of high‐density polyethylene is studied at draw rates of 2.5 × 10−2 to 25 mm/min and at temperatures of −40° to 80°C. Effect of temperature and draw rate on necking stress is interpreted in terms of viscoelastic flow of amorphous phase accompanying orientation of crystallites.

Photoconduction of High-Density Polyethylene

Japanese Journal of Applied Physics, 1967
A photo-current was observed in high-density polyethylene when a 40 micron-thick sample was exposed to low-intensity white light from a tungsten lamp. A large photo-current was found when a sample had been pre-irradiated with high-energy electrons.

Granulomatosis of bone from high density polyethylene

Injury, 1982
Granulomatous reaction by bone to high density polyethylene can occur if the rate of wear and the volume of the resulting wear products is abnormally great. The phenomenon was found in 6 of 11 patients who had had a Monk soft-top prosthesis inserted more than two years before.
