A wide range of physical and mechanical properties can be achieved in polymer/polymer blends by variation of such features as the molecular structure of the components, blend composition, morphology, and processing conditions [1–6]. If the two components of a binary blend are completely miscible at the molecular level, only a single phase will be present, and the glass transition temperature T g of the blend will lie between the respective T g's of the two components. This occurs, for example, in blends of polystyrene (PS) and poly (2, 6 dimethyl phenylene oxide) (PPO), for which the blend T g varies linearly with composition over the entire range [7]. The properties of such single-phase blends are reported to fall between those of the components and not to differ appreciably from values expected based on the simple rule of mixtures [2, 8]. On the other hand, if the two components of the blend are completely immiscible, two distinct phases will be present, each of which will have its own T g that is uninf...

1. INTRODUCTION 1.1. Background Schlenk was the first to use the term inclusion compound (IC) to describe the crystalline adducts in which one component (host molecule) crystallizes into a matrix, isolating the second component (guest molecule) into cavities of well-defined geometry [1]. Most of the ICs reported have been described as inclusion compounds or clathrates in the literature. In addition, there are many more compounds that are described as solvates, and many of these must surely be ICs [2].

Cerium(IV) ions are versatile reagents for the oxidation of numerous functional groups in organic synthesis, as well as in transition metal chemistry. They are also employed [1] to achieve nitration, hydroxylation, rearrangement, addition of carbonyl compounds to 1, 3-dienes, hemolytic malonylation of aromatic hydrocarbons, alkoxyiodination, nitratoiodination, and more. Most of these transformations open up a broad applicability due to their mild reaction conditions, fast conversions, and convenient work-up procedures.

1. INTRODUCTION The two principal commercial polyamides are poly(hexamethylene adipamide) (nylon 66) and polycaprolactam (nylon 6). They are produced by direct amidation of a diacid with a diamine and ring-opening polymerization of ɛ-caprolactam, respectively. Poly(hexamethylene adipamide) is synthesized by hexamethylene diamine and adipic acid [1]. A stoichiometric balance of amine carboxylic group is readily obtained by the preliminary formation of a 1:1 ammonium salt:

1. INTRODUCTION The prediction of polymer crystallization behavior at a reasonable semiquantitative level of accuracy is important in assessing processability and performance. For example, in both polypropylene (PP) [1–3] and poly(ethylene terephthalate) (PET), the interplay of the effects of rheology and crystallization kinetics under various types of fabrication conditions is crucial in determining the semicrystalline morphology. In turn, morphology affects the mechanical, optical, and gas barrier properties of the fabricated articles. On the other hand, since many important plastics fabrication processes are carried out with the polymer in semicrystalline state (below the crystalline melting temperature, but above the amorphous glass transition temperature), while others are carried out from the melt and above the recrystallization temperature, the crystallization kinetics and the morphology, in turn, also affect the processing of the polymer by these fabrication methods.
