| Abstract: | The kinetics of growth of the spherulites in polymers crystallized from the melt and the structure of the spherulites and the lamellae of the semi-crystailine polyrnere are reviwed. The growth rate of a spherulite is controled by three main processes: the formation of a critical nucleus on the front of the growing crystal,the reeling-in of the crystallizable units through the crystal amoughous interface and the interdiffusion of the mass center of the two components. The effect of the molecular weight on the crystallization kinetics and the growth rate in the misicible blends of the crystalliz ing and noncrystallizing polymers are discussed. |
