Rubber-like tensile behaviour of yielded high-impact polystyrene

Strain-induced deformation mechanisms of polylactide plasticized with acrylated poly(ethylene glycol) obtained by reactive extrusion

“…The tensile behavior of pPLA is therefore influenced by the glassy/rubbery state, the presence of the rigid crystalline phase and the presence of the rubbery poly(Acryl‐PEG) inclusions. At 20 °C, the tensile curve of pPLA is similar to that of rubber‐toughened amorphous polymers such as high‐impact polystyrene drawn below their T g . In this case, the tensile curve is characterized by an initial viscoelastic stage where the stress drastically increases with strain until the yield point.…”

“…At 20 ∘ C, the tensile curve of pPLA is similar to that of rubber-toughened amorphous polymers such as high-impact polystyrene drawn below their T g . 25,26 In this case, the tensile curve is characterized by an initial viscoelastic stage where the stress drastically increases with strain until the yield point. At the onset of the viscoplastic stage the stress drops resulting in a strain-softening stage and then finally increases resulting in a strain-hardening stage.…”

Investigation of the phase morphology of dynamically vulcanized PVC/NBR blends using atomic force microscopy

“…Some authors have reported that blend morphology is also very important in deciding about the ultimate properties of polymer blends 15, 16. In tensile measurements, stress–strain curves can reveal information about the deformation and the energy consumed before failure, in addition to ultimate strength and elongation properties 17, 18…”

Combustion and fire retardance of poly(2,6-dimethyl-1,4-phenylene ether)–high-impact polystyrene blends. I. Morphological aspects

“…An Agema 880 apparatus was used, equipped with an MCT detector, cooled at liquid nitrogen temperature, operating in the [8][9][10][11][12] pm range. The emissivity value, t = 0.95, was used for the computation of the temperature values.…”

“…The temperature of the surface of the specimen not involved in the flame or of the charred burned section immediately after extinguishment of the flame in the UL 94 test was measured by infrared thermography. An Agema 880 apparatus was used, equipped with an MCT detector, cooled at liquid nitrogen temperature, operating in the [8][9][10][11][12] pm range. The emissivity value, t = 0.95, was used for the computation of the temperature values.…”
