Fluxional Monomers Remodel Crystallinity at Low Loadings in Diketopyrrolopyrrole Co‐Thienothiophene Conjugated Polymers

open access: yesAngewandte Chemie, EarlyView.
Bullvalene is a fluxional molecule capable of adopting numerous conformations spontaneously; just like a Rubik's Cube. In this paper, we explore the incorporation of bullvalene into the backbone of a highly rigid conjugated polymer semiconductor and observe that the inherent fluxionality reduces average crystallite size.

The Melting Line, the Crystallization Line, and the Equilibrium Melting Temperature of Isotactic Polystyrene

Macromolecules, 2002
It is known that the determination of the equilibrium melting temperatures of polymers which show recrystallization during heating is a difficult problem. This is mainly due to the difficulty encountered in determining the melting temperature of the initial lamellae which exist before recrystallization takes place.

Relationships Between Melting Temperature, Maximum Crystallization Temperature and Glass Transition Temperature

Polymer, 1990
Abstract Empirical prior rules in melting temperature, Tm, maximum crystallization temperature, Tcmax, at which crystal growth rate is maximum, and glass transition temperature, Tg, were investigated to find a phenomenological and theoretical background. Relationships among Tm, Tcmax and Tg were formulated as T cmax T m = C (C +
