Rheological and thermal properties of m-LLDPE blends with m-HDPE and LDPE
TL;DR: In this paper, the dynamic and steady state behavior of metallocene linear low density polyethylene (m-LLDPE) blended with high-density polyethylen and with low-dense polyethylenes (LDPE), was measured in parallel plate rheometer at 160, 180, and 200 degrees C. The results were consistent with the rheological properties of these two series of blends.

Correlations between composition and crystallinity of LDPE/HDPE blends
Marilda Munaro,Leni Akcelrud +1 more
TL;DR: In this paper, the average degree of crystallinity was calculated, allowing the establishment of quantitative relationships between composition and crystallinity, and shifting of the α-relaxation was also correlated with shifting of α-transition.

Rheological, thermal, and morphological properties of low-density polyethylene/ultra-high-molecular-weight polyethylene and linear low-density polyethylene/ultra-high-molecular-weight polyethylene blends
TL;DR: In this article, the dynamic rheological behavior of low-density polyethylene (LDPE)/ultra-high-molecular-weight polyethylen (UHMWPE) blends and linear LDPE/UHMMPE blends was measured in a parallel-plate rheometer at 180, 190, and 200°C.

TL;DR: In this paper, the gear predictor -corrector is used to calculate forces and torques in a non-equilibrium molecular dynamics simulation using Monte Carlo methods. But it is not suitable for the gear prediction problem.

A unified formulation of the constant temperature molecular dynamics methods
TL;DR: In this article, the authors compared the canonical distribution in both momentum and coordinate space with three recently proposed constant temperature molecular dynamics methods by: (i) Nose (Mol. Phys., to be published); (ii) Hoover et al. [Phys. Rev. Lett. 77, 63 (1983); and (iii) Haile and Gupta [J. Chem. Phys. 79, 3067 (1983).

DREIDING: A generic force field for molecular simulations
TL;DR: The DREIDING force field as discussed by the authors uses general force constants and geometry parameters based on simple hybridization considerations rather than individual force constants or geometric parameters that depend on the particular combination of atoms involved in the bond, angle, or torsion terms.

TL;DR: In this paper, a series of small angle neutron scattering (SANS) experiments on blends of linear and branched polyethylenes were performed to investigate the level of branching that is required to phase separate the system.
