Homopolymers, crystallization kinetic homogeneous nucleation

Taking into account all of the results presented above, we can conclude that in order to be sure that homogenous nucleation is indeed present (even when first-order crystallization kinetics is encountered), the crystallization rate must exhibit a dependence on the volume of the droplets or on the cube of the particle diameter. Additionally, even in extremely small droplets comparable to only a few chains in size, the nucleation still occurs within the interior of the droplets. Furthermore, the homogeneous nucleation event is independent of the molecular weight and of the molecular architecture (at least when comparing homopolymers and diblock copolymers). The homogeneous nucleation temperature is a function of the particle size. In certain cases, when the droplets size is nanometric, modifications of the crystal structure of the polymer as compared with that usually observed in the bulk have been reported. The effects of superficial nucleation are important and should be taken into consideration.
