Phase Equilibria and Interdiffusion in Bimodal High-Density Polyethylene (HDPE) and Linear Low-Density Polyethylene (LLDPE) Based Compositions

“…A downward trend was also observed for the crystallization curve ( Figure 1 b). Similar effects were described earlier in [ 7 , 23 , 24 , 25 ].…”

“…Thus, based on the results of thermochemical measurements, one can assume mutual solubility of the components both in the melt and in the solid crystalline state. Note that some researchers [ 7 , 23 , 24 , 25 ] believe that a single thermal peak cannot be regarded as unequivocal evidence of co-crystallization of macromolecules of polyolefins of different architecture.…”

“…In the literature, increased interest in such compositions is associated with the lower cost of polymers and the possibility of combining the positive properties of chemically similar types of PE, that have different density, molecular weight, rheological and performance properties, in one material. Mixtures of low-density polyethylene (LDPE) with monomodal copolymers of α-olefins LLDPE (butene-1, hexene-1, octene-1), high-density polyethylene (HDPE) with LDPE [ 7 , 8 , 9 ], HDPE with LLDPE [ 2 , 7 , 10 ] have been studied and characterized in detail and are widely used in film, membrane, and packaging production [ 11 , 12 , 13 , 14 ]. In these works, considerable attention is paid to the analysis of their rheological, mechanical, thermal, structural and morphological properties.…”

Application of mean-field theory in PP/EVA blends by focusing on dynamic mechanical properties in correlation with miscibility analysis

“…Blending of two or more polymers to achieve specific properties that individual materials do not possess is one of the most applicable techniques widely practiced [1,2]. The majority of the polymer blends are immiscible or incompatible on a molecular scale for thermodynamic reasons such as small combinatorial entropy and positive enthalpy of mixing.…”

Elektrik Kontak Kesicilerde Kullanabilmek için Aşınma Dirençli Polimer ve Polimer Kompozit Malzemelerin Belirlenmesi

“…Polistiren (PS) ve PPE polimerlerinin termodinamik olarak karışabilirliği olduğundan PPE/PS karışımları son yıllarda endüstriyel olarak en iyi bilinen polimer karışımı haline gelmiştir. PPE polimeri aynı zamanda poliamitler [16,17], poli-etilen-tereftalat (PET) [18], polipropilen (PP) [19] ve yüksek yoğunluklu polietilen [14] polimerleri ile de kullanılabilmektedir.…”
