Rheological and morphological analysis of irradiated high and low density polyethylene samples

چکیده
The influence of intensity the ?-irradiation on commercial high and low density polyethylene (LDPE HDPE) granules (Kazanorgsintez PJSC, Kazan, Tatarstan, Russia) their rheological morphological properties at irradiation doses 5 10 kGy was studied. Experiments in oscillation mode revealed an increase dynamic moduli values with increasing radiation dose compared to initial samples. At same doses, HDPE samples LDPE ones showed greatest changes properties, while zero shear viscosity increased by order magnitude one kGy. Morphology analysis supramolecular structures cob-web-type for irradiated sample comparison sample, which may indicate formation branched under ?-irradiation.

Linear low-density polyethylene (LLDPE) based composites were prepared by melt compounding with 1, 2, 3 and 4 vol% of various kinds of amorphous silicon dioxide (SiO2) microand nanoparticles. Dynamic rheological tests in parallel plate configuration were conducted in order to detect the role of the filler morphology on the rheological behaviour of the resulting microand nanocomposites. A strong...

HDPE monofilaments were obtained using different extruders and drawn by post-extruder equipments. After solidification, drawn and undrawn monofilaments (draw ratio 7:1) were irradiated with 10 MeV electron beams in air at room temperature at 25, 50, 75, 100 and 125 kGy dose ranges to induce a network structure. HDPE crosslinking was studied on the basis of gel content measurements. The fibers w...
