TL;DR: In this paper, the effectiveness of functionalized polymers as compatibilizers for polypropylene (PP) homopolymer blends was evaluated in terms of improvement in impact properties and blend morphology.

TL;DR: The experimental results show that the releases of TPH from these hydrogels are dependent upon the composition of the hydrogel, the type of component, the possible interactions between two component polymers, as well as external temperature.

TL;DR: In this paper, detailed viscometric and ultrasonic velocity studies have been conducted on solutions of blends of poly(methyl methacrylate) with poly(vinyl acetate), poly (vinyl chloride) and poly(polystyrene) over an extended range of concentrations and temperatures.

TL;DR: A series of blends of poly(lactic acid) (PLA) and poly(e-caprolactone) (PCL) with different mass ratio were prepared by means of the melt blending method to study their crystallization, miscibility, morphology, and thermal and mechanical properties as discussed by the authors.
Abstract: A series of blends of poly(lactic acid) (PLA) and poly(e-caprolactone) (PCL) with different mass ratio were prepared by means of the melt blending method to study their crystallization, miscibility, morphology, and thermal and mechanical properties. The result of DSC tests showed that the melting temperatures of PLA and PCL shifted toward each other, and that the largest shift appeared at the PLA70PCL30 blend. This result reveals that the PLA70PCL30 blend gives the strongest interaction intensity among the blends. Combined the result of dynamic mechanical analysis and SEM morphologies, it was found that PLA and PCL form a partial miscible blend, in which an amount of amorphous PCL (amorphous PLA) is dissolved in the PLA-rich phase (PCL-rich phase), leading to a depression of the Tg. value. The polarized optical micrographs showed that PCL can serve as a nucleating agent to promote PLA crystallization in the PLA/PCL blend. Moreover, the PLA70PCL30 blend gave the largest growth rate of PLA spherulite. Final...

TL;DR: In this article, the coarsening of co-continuous morphologies in polymer blends with annealing is studied, demonstrating the effect of interfacial tension, viscosity and also physical cross-links in blends with thermoplastic elastomers.
