This contribution provides an overview of the current state of art of spherulite growth rate in binary polymer blends. A detailed analysis of the various factors that contribute to increase or decrease the growth rate of spherulites is reported and supported by several examples. The reported results

## Abstract Isothermal radial growth rates (__G__) of isotactic polypropylene (iPP) spherulites in immiscible blends with a polyethylene based ionomer (1) partially neutralized with Zn^+2^, (2) completely acidified, and (3) completely esterified have been determined at crystallization temperatures
Growth rates of crystallized fractions of poly(3,3-diethyl oxetane) covering the range ~n = 10,000-800,000 have been studied by polarized light microscopy at crystallization temperatures from 51.5 to 58~C. It has been found that the growth is linear and only spherulites are formed in the temperature
