Special Issue Information

Dear Colleagues,

Natural and synthetic polymers are macromolecules that are broadly applied in our daily life, such as celluloses, starches, silks, polyethylene, polypropylene, polystyrene, poly(ethylene terephthalate), and nylons. Their properties for versatile applications are mainly determined by their molecular and aggregation structures. The Special Issue of this journal aims to expose the importance of structure-property relationships in polymers and specialty applications. The authors and their contribution titles are selected to cover the broad range of this field. Theories, simulations, and experiments are welcome to reflect the cutting-edge knowledge on this interdisciplinary subject. The structure-property relationship will remain the central topic in polymer physics and promises a bright future for the materials genome of polymers.

In this work, the melt crystallization behavior and the solid phase transition of isotactic polybutene (PB) were studied in the polybutene/high-density polyethylene (PB/PE) blends covering the whole composition range. For the dynamic cooling crystallization, PE exhibits almost the same crystallization temperature in all blends, whereas PB exhibits a distinct non-monotonic dependence on the composition ratio. Combining the ex situ X-ray diffraction and in situ Fourier transform infrared spectroscope, it was demonstrated that during cooling at 10 °C/min, the presence of at least 70 wt% PE can induce the formation of form I′ directly from the amorphous melt. The detailed relations of polymorphism with temperature were systematically investigated for the PB/PE blends. Different from the formation of the sole tetragonal phase with ≤50 wt% PE, the trigonal form I′ could crystallize directly from amorphous melt with ≥60 wt% PE, which can be further enhanced by elevating the temperature of isothermal crystallization. Interestingly, the critical lowest temperature of obtaining pure form I′ was 85 °C with 70 wt% PE and decreased to 80 °C as the PE fraction was increased to 80 wt%. On the other hand, the spontaneous phase transition from the kinetically favored form II into the thermodynamically stable form I was also explored with X-ray diffraction methods. It was found that at the room temperature, phase transition kinetics can be significantly accelerated by blending at least 70 wt% PE. Full article
