Preparation of ultra high molecular weight polyethylene with MgCl2/TiCl4 catalysts: Effect of temperature and pressure

“…9 UHMWPE was unique and was distinctly different from its homolog as can be seen from the ultra high molecular weight. 10 Because of its ultra high molecular weight, UHMWPE has excellent in impact resistance, abrasion resistance, sliding properties and chemical resistance. 10 As such, UHMWPE was exploited in a wide spectrum of applications such as bearings, pulleys, and as a lining of trucks or dock guards.…”

Fabrication of 3D biocompatible/biodegradable micro-scaffolds using dynamic mask projection microstereolithography

“…This was achieved using DEF as a diluent, a heated vat, and a settling time of 30 s, and although micro-fabrication was successful, some dimensional inaccuracies undoubtedly resulted from temperature variations within the vat (i.e., from the free surface during settling). In addition to the molecular weight affecting the viscosity, the overall manufacturability of polymers, in general, are inversely proportional to the molecular weights of polymers (Aiello and Mantia, 2001). That is, on increasing the molecular weight of polymers, the polymers are more difficult to use in manufacturing due to an increased melt viscosity (Menon et al, 2002), despite the strength of the polymer increasing with viscosity.…”

Size effects of silica on the viscosity of ultra‐high molecular weight polyethylene and its disentanglement mechanism

“…The incorporation of various flow modifier is a convenient and effective method for optimizing the properties of UHMWPE. 5,[9][10][11][12][13] The common flow modification methods are the addition of high melt flow rate polymers in UHMWPE. When choosing a polymer as a flow modifier it is important to consider not only its own fluidity but also its compatibility with UHMWPE.…”

“…Many efforts have been attempted to develop UHMWPE with low viscosity and high flowability. The incorporation of various flow modifier is a convenient and effective method for optimizing the properties of UHMWPE 5,9–13 . The common flow modification methods are the addition of high melt flow rate polymers in UHMWPE.…”
