The relation between the growth rate and crystallization temperature of low molecular weight fractions of isotactic poly(propylene) follows a pattern similar to poly(ethylene oxide) and polyethylene. Figure 9.93 is a plot of log growth rate against the crystallization temperature for two fractions of isotactic poly (propylene), M = 20(X) and = 3000.(319) The curves are similar to those of the other...

The dependence of the overall crystallization rate on the composition of these two blends differs from those of the growth rates.(77) The half-time for syndiotactic poly(styrene) crystallization is plotted against the crystallization temperature for both type blends in Fig. 11.33. The half-times for the pure syndiotactic polymer are represented again by the sohd circles. For this type of measurement the halftimes increase with the addition of either poly(vinyl methyl ether) or PPO. The addition of poly(vinyl methyl ether) causes a larger increase in the half-time and thus a greater reduction in the crystallization rate. The overall crystallization rate is a reflection of both initiation and growth of crystalUzation. Both of these processes... [Pg.326]
