TL;DR: In this paper, the authors investigated the chain architecture dependence of the retention behavior of block copolymers in the temperature gradient interaction chromatography (TGIC) and liquid chromatography at the critical condition (LCCC).

TL;DR: In this paper, a secondary polymer battery is provided with: a cathode containing a current collector made of an electrically conductive substrate and a composition placed on said current collector, said composition including i) one or more transition metal compounds selected among a transition metal and transition metal salt of the formula MXn, wherein M is transition metal, X is a halogen negative ion, and n is an integral number between 1 to 6; ii) a matrix polymer which has a basic functional group with affinity for the transition metal species; (b) a polymer electrolyte containing a lithium

TL;DR: Temperature gradient interaction chromatography (TGIC) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) were applied for the characterization of highly branched polystyrenes (PS) prepared by linking living polystyryl anions using 4-chlorodimethylsilylstyrene showing an unexpectedly high resolution.

TL;DR: The retention behavior of star-shaped polystyrene (PS) at the liquid chromatographic critical condition of linear PS was investigated in this paper, where three PS samples were prepared by anionic polymerization of styrene and subsequent linking of the polystyryl anions with divinylbenzene.

TL;DR: In this article, star polystyrenes were synthesized from polystyryllithium with an incremental procedure in which equally divided portions of divinylbenzene (DVB) were added periodically.
