What Are Blends and Alloys of Linear Polymers?
International Journal of Polymeric Materials and Polymeric Biomaterials, 1992Abstract The expression “polymer blends and alloys” is widely used at present. However, until now there is no precise wording to describe what kind of binary or multicomponent mixtures should be referred to as “polymer alloy” and what kind of “polymer blend.” Even in the recently published superb and fundamental book by Utracki,1 only qualitative ...

Makromolekulare Chemie. Macromolecular Symposia, 1993
AbstractThe state of thermodynamic miscibility of a polymer blend and its resulting phase behavior and mechanical properties is largely determined by the balance between enthalpic and entropic contributions to the free energy of mixing. Recent applications of this thermodynamic consideration are reviewed for a variety of binary and ternary blends of ...

Polymer alloys and blends: Recent advances
Canadian Journal of Chemical Engineering, 1991AbstractPolymer alloys and blends represent one of the fastest growing sectors of the plastics industry. To a large degree, the emphasis has now shifted from developing blends in the reactor to their creation through melt mixing on processing equipment such as extruders.

Theoretical aspects of polymer blends and alloys
1993An attempt has been made in this chapter to provide a sound basis for understanding the mechanical behaviour of polymer blends and alloys. The presentation has not been over-simplified, for the author agrees with the point of view of Treloar [1] in the preface in the preface to the first edition of his book The Physics of Rubber Elasticity that ‘… if ...

The reactor granule technology: A revolutionary approach to polymer blends and alloys
Macromolecular Symposia, 1994AbstractThe new plastic materials frontier in general and in thermoplastic polyolefins in particular developed in the last years and into next century are and will be represented by polymer alloys. The new trend in polymer alloy is to obtain them from monomer directly in the reactor, replacing the polymer blends previously made by mechanical melt ...

Flow induced deformation of dual‐phase continuity in polymer blends and alloys. Part I
Polymer Engineering & Science, 1999AbstractA hypothesis for formation of bi‐continuous phase structures in immiscible polymer blends is proposed. It is based on the observation that a critical volume fraction φcr for the dual continuity of phases may be calculated considering the geometry of the dispersed phase. The knowledge of the form of discrete domains at the volume fractions φ <

Journal of Applied Polymer Science, 1990
AbstractThe composition of polymer blends and alloys and the crystallinity and crystallite size/perfection of each of the components are determined by X‐ray diffraction (XRD) methods. A profile‐fitting procedure is used to resolve the XRD scan into crystalline and amorphous peaks corresponding to each of the polymers.

Effect of Substrate on the Properties of Polymer Alloys and Blends
Journal of Adhesion, 1992Abstract The thermodynamic aspects of the influence of the solid surface on the properties and adhesion of polymer blends and alloys are discussed. It is shown that under the influence of the surface the properties and composition of the interphase may be changed.
