This Chapter reviews the manufacturing, properties, and applications of ultra-high molecular weight polyethylene (UHMWPE) fibers and composites. UHMWPE fibers like Dyneema from DSM and Spectra from Honeywell are made by gel-spinning, possessing impre

The bio-based and biocompostable semi-crystalline poly(L-lactide), PLLA, suffers from slow crystallization rate. Oxalamide compounds are tailor-made as novel self-assembly-type nucleators in this work, which altered significantly the crystallization

Superior properties such as high strength, toughness and transparency of fully biobased poly(lactide) (PLA) were achieved simultaneously without any external modifiers. The improvement in properties is well explained by a structural/morphological stu

Poly(β-hydroxybutyrate), PHB, is a bio-based and biodegradable material. However processing and application of the PHB are disturbed by its low crystallization rate. In this manuscript the crystallization behavior of the PHB was improved via incorpo

Maleic anhydride (MA) was grafted onto poly( β -hydroxybutyrate) (PHB) chains by using styrene (St) as co-monomer and dicumyl peroxide (DCP) as free-radical initiator. The grafting degree of MA was increased from 0.2 wt% to 0.9 wt% with the St/MA ra

Fully bio-based and biocompostable poly (lactic acid)/poly (β-hydroxybutyrate-co-β-hydroxyvalerate) (PLA/PHBV) blends were prepared by melt compounding. PHBV with a high β-hydroxyvalerate content (40 mol%) was used in this work. Miscibility betwee

Poly(lactic acid)/poly(ethylene-co-vinyl acetate)/starch (PLA/EVA/starch) ternary blends were prepared by multi-step melt processing (reactive extrusion) in the presence of maleic anhydride (MA), benzoyl peroxide and glycerol. The effects of MA and g

Deformability of molten ultra-high molecular weight polyethylene (UHMWPE) was studied in the plane-strain compression at the temperature from a range of 145–165°C. Two grades of UHMWPE were tested—a commercial one synthesized in a slurry process

We investigate the linear and non-linear rheological behavior in shear of a concentrated solution of “dumbbell” polystyrene with long linear backbone and dense short brushes at both ends and compare it with corresponding linear polymers. This typ

Understanding of the physical characteristics of a polymer requires molar mass determination. For the commercially available polymers, having average molar mass below 1 000 000 g/mol, chromatography is the method that is often applied to determine th
