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 ...

Nucleation of Iow density polyethylene by high density polyethylene

Journal of Materials Science Letters, 1988
The spherulitic morphology of semicrystalline polymers can be influenced by nucleating agents. With high concentrations of such agents a morphology results which consists of small spherulites. This effect is used, for example, to increase the optical transparency of films or to increase the toughness [1].

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.

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.

Linear low‐density polyethylene/high‐density polyethylene blends: Effect of high‐density polyethylene content on die swell and flow instability

Journal of Applied Polymer Science, 2020
AbstractThis work aimed to evaluate the effect of high‐density polyethylene (HDPE) content and of shear rate on the die swell and flow instability of linear low‐density polyethylene (LLDPE)/HDPE blends. The results showed that the die swell of the LLDPE/HDPE blends increased with the increase in the shear rate.
