Effect of fillers on the supramolecular structures and mechanical properties of crystalline polymers

Interactions of Clay Minerals with Organic Polymers. Some Practical Applications

“…On crystallization, the clay particles tend to become concentrated in the interspherulitic regions reducing the mobility of the polymer in these areas and preventing their regrouping in the crystalline phase. As a consequence, the average size of the spherulites is decreased, this reduction being greater as the size of the filler particles is decreased (Solomko et al, 1966).…”
