Evaluation of Philips and Ziegler-Natta high-density polyethylene degradation during processing in an internal mixer using the chain scission and branching distribution function analysis
(Elsevier B.V., 2006-10-01)
The oxidative and thermo-mechanical degradation of HDPE was studied during processing in an internal mixer under two conditions: totally and partially filled chambers, which provides lower and higher concentrations of ...

The role of chain scission and chain branching in high density polyethylene during thermo-mechanical degradation
(Elsevier B.V., 2004-12-01)
The mechanical and thermo-oxidative degradation of high density polyethylene (HDPE) was measured in a twin-screw extruder using various processing conditions. Two types of HDPE, Phillips and Ziegler-Natta, having different ...
Efficiency of Different Chain-linking Agents in the Synthesis of Long-chain Branched Polypropylene. Molecular, Thermal and Rheological Characterization
(Taylor, 2017-09)
Long-chain branched polypropylenes were synthesized from a maleic anhydride grafted polypropylene (PPg). Different levels of branching were generated by reactive processing using four chain-linking agents: glycerol, ...
Molecular identification of a further branched-chain aminotransferase 7 (BCAT7) in tomato plant

Morphological raman analysis of short chain branched ethylene and propylene metallocenic copolymers
(Elsevier, 2018-05)
Spectroscopic features in the Raman spectra of semicrystalline polyolefins that characterize different phase morphologies are reported. With growing incorporation of different 1-olefins, changes in the spectra due to ...

Emulsion Polymerization of Isoprene: Mathematical Model for Long Chain Branching
(John Wiley & Sons Inc, 2011-12)
For a batch emulsion polymerization of isoprene at 10 °C in the presence of a chain transfer agent, a previous mathematical model [Minari et al., J. Appl. Polym. Sci. 2010, 116, 590] was extended for predicting the molecular ...
