T h e mechanical relaxations of isotropic and oriented linear low-density polyethylene have been studied between -180 and 90Β°C by the use of a torsion pendulum (1 Hz), a dynamic tensile apparatus (5-90 Hz), and a longitudinal wave attenuation technique (10 MHz). The five independent elastic moduli o
The crystallization of a series of low-density polyethylene (LDPE)-and linear low-density polyethylene (LLDPE)-rich blends was examined using differential scanning calorimetry (DSC). DSC analysis after continuous slow cooling showed a broadening of the LLDPE melt peak and subsequent increase in the
Three commercial LLDPE samples with ethyl, hexyl and isobutyl branches were fractioned by cross chromatographic fractionation methods, i.e. a combination of SEC and TREF techniques. The fractions with different molecular weight distribution (MWD) and short chain branching distribution (SCB) were obt
