Effect of gamma irradiation on density and thermal expansion changes of uniaxially oriented linear low-density polyethylene
(Radiation Physics and Chemistry, 1999)
The density and thermal expansion behaviour of linear low density polyethylene, over the temperature range from -95 degrees to + 10 degrees C, is measured. The influence of drawing on density and thermal expansion behaviour ...
Stress relaxation in high density polyethylene. Effects of orientation and gamma radiation
(Polymer Journal, 1999)
The stress relaxation of unoriented (lambda = 1) and oriented (lambda = 9) high density polyethylene (HDPE) was studied for different levels of radiation (0, 100, 300, and 500 kGy). The relaxation behavior is analyzed in ...
New rotational analysis of the B-2 Sigma(+)-X-2 Sigma(+) bands in (GaO)-Ga-69-O-16 and (GaO)-Ga-71-O-16
(Journal of Molecular Spectroscopy, 1999)
In the emission spectrum of the (GaO)-O-16 molecule, the 0-0 and 1-0 bands of the B-X system have been rephotographed by means of conventional high-resolution spectroscopy. Clear resolution on the rotational structure near ...
Effect of gamma irradiation on the dielectric relaxation of uniaxially oriented low density polyethylene
(Polymer International, 1999)
The dielectric loss tangent of unirradiated acid irradiated low density polyethylene (LDPE) samples was measured as a function of temperature, from 50K to room temperature, in directions normal and parallel to that of ...
Effects of gamma irradiation on the stress relaxation of drawn ultrahigh molecular weight polyethylene
(Radiation Physics and Chemistry, 1999)
Effects of high energy radiation on stress relaxation behavior of unoriented (lambda = 1) and oriented (lambda = 9) ultrahigh molecular weight polyethylene (UHMWPE) were investigated. As in a previous study, the stress ...
