Random copolymers exhibit diverse crystallization behavior depending on whether
comonomers are excluded or included in the crystalline phase. To understand the …

Stacks of crystalline lamellae all having a uniquely oriented hexagonal shape, referred to as
“3D (three-dimensional) single crystals”, were obtained via isothermal crystallization of …

Biodegradable random copolymers were successfully synthesized by melt
polycondensation of poly (butylene succinate)(PBS) and salicylic acid (SA). The obtained …

Through fixing the orientation of oriented polyethylene (PE) thin film during melt-
recrystallization with the help of a vacuum evaporated thin carbon layer, the isothermal melt …

Blends of a small amount of poly (vinylidene fluoride)(PVDF) with miscible low-melting-point
poly (1, 4-butylene adipate)(PBA) were prepared, and the structures of PVDF formed in the …

In the crystallization of polymers, besides monolamellar polymer crystals, stacks of
correlated lamellae with a unique orientation and signatures of single crystals have often …

Abstract Poly (ethylene succinate)(PESu), upon crystallization with a morphology‐
modulating diluent and at low degree of supercooling, forms peculiarly novel sector‐face …
