TL;DR: A kinetic model for the solid-state polymerization of poly(bisphenol A carbonate) in a single particle has been developed and used to investigate the broadening of molecular weight distribution as a result of slow condensate diffusion as discussed by the authors.

Polymer Crystallization By Chemical Nucleation
TL;DR: In this article, the mechanism of action of organic nucleating agents such as sodium benzoate and its derived salts completely differs from the generally accepted model, at least in the case of polyesters.

TL;DR: In this article, a polyethylene oxide containing high concentrations of Cu(ll) chloride has been studied as a function of temperature and a new hexagonal type structure with unit cell dimensions of a = 6.52 and c = 19 is seen to occur for high concentration of the copper chloride.
