## Abstract The number of mmrβ and rrmβbased structures which occur necessarily whenever an isotactic or a syndiotactic sequence breaks off respectively; the extent to which they are isolated or are extended to atactic sequences, and the fact that the mmr repeating sequence, especially when it take
Binary blends of poly(viny1 chloride) (PVC) and chitin-graf-poly(2-methyl-2-oxazoline) showed miscibility in the blend fraction range of the latter lower than ca. 10 wt.-Yo. The glass transition temperature of PVC, which was determined by differential scanning calorimetry, changed to lower temperatu
