Effect of the TrFE Content on the Crystallization and SSA Thermal Fractionation of P(VDF-co-TrFE) Copolymers
(MDPI, 2022-09-08)
In this contribution, we study the effect of trifluoro ethylene (TrFE) comonomer content (samples with 80/20, 75/25, and 70/30 VDF/TrFE molar ratios were used) on the crystallization in P(VDF-co-TrFE) in comparison with a ...
Temperature modulated DSC for composition analysis of recycled polyolefin blends
(Elsevier, 2022-09)
Post-consumer plastic waste contains blends of numerous types of polyethylene (PE) and isotactic polypropylene (i-PP), whose recycling is challenging due to the complexity of this waste stream. A comprehensive knowledge ...
Surface Nucleation of Dispersed Droplets in Double Semicrystalline Immiscible Blends with Different Matrices
(Wiley, 2022-11)
When a minor semicrystalline phase is dispersed in an immiscible blend with another polymer in the form of isolated droplets, its crystallization behavior is dominated by nucleation. In particular, nucleation can occur in ...
Effect of compatibilizer addition on the surface nucleation of dispersed polyethylene droplets in a self-nucleated polypropylene matrix
(Elsevier, 2022-12)
A significant portion of the global plastics market encompasses the production of polyolefin materials and especially polypropylene (PP) and polyethylene (PE), as commodity polymers with a wide range of applications. ...
Understanding polymer nucleation by studying droplets crystallization in immiscible polymer blends
(Elsevier, 2023-01)
This Feature Article reviews our recent work on the nucleation and crystallization of finely dispersed semicrystalline polymeric droplets in immiscible matrices. Droplets dispersions can be used as a toolbox to investigate ...
Surface-enhanced nucleation in immiscible polypropylene and polyethylene blends: The effect of polyethylene chain regularity
(Elsevier, 2023-08)
In blends where polyethylene (PE) is the minor component dispersed in an isotactic-polypropylene (PP) matrix, an enhancement of the crystallization rate of PE was found when the crystallization temperature of the matrix ...
Disappearance of Melt Memory Effect with Comonomer Incorporation in Isodimorphic Random Copolyesters
(ACS, 2023-10)
Melt memory effects in polymer crystallization have attracted much attention in the past few years. Although progress has been made in understanding how the chemical structure of polymers can affect melt memory, there are ...
