“…Although polymer blends have been studied very extensively in the recent past [1][2], most attention has been paid to binary blends uncompatibilized and compatibilized by suitable interfacial agents. Recently, three-phase ternary blends have received some attention [3][4][5][6][7][8], the purpose being to launch new materials on the market place and to evaluate whether multicomponent plastic wastes are worth being recycled.…”

The weight ratio of PE and PS in ternary PS/SBR/PE blends has been changed at constant SBR content (25 wt%). When the matrix is either PE or PS, the dispersed phase has a core-shell structure with SBR forming the shell. The size of the core expectedly increases with the content of the core-forming polymer. In some composition range, the three phases are simultaneously continuous, SBR being localized in between the cocontinuous PE and PS phases. The ultimate mechanical properties of the ternary blends containing SBR/PE and SBR/PS core-shell dispersed phases are close to the properties of the PS/SBR and PE/SBR binary blends, respectively. Some synergism in the elongation at break of the ternary blends is observed when core-shell SBR/PS phases are dispersed in PE matrix.

“…Several polymer pairs are known to be miscible or partially miscible and many of these have become commercially important [2]. Considerable attention has been given to the origins of miscibility and to binary polymer-polymer phase diagrams.…”

“…Considerable attention has been given to the origins of miscibility and to binary polymer-polymer phase diagrams. It is usually observed that high molar mass polymer pairs, showing partial miscibility, exhibit phase diagrams that indicate a lower critical solution temperature (LCST) [2,[45][46][47]. In a polymer blend that exhibits LCST behaviour, the miscibility is higher at low temperatures.…”

“…The strong correlations that exist between the morphology, the processing and the physical and the mechanical properties in multicomponent polymeric systems are well-recognised [1,2]. These aspects and correlations are a consequence of the interactions that occur between the various components of polymer-based systems.…”

“…This is because such intermolecular forces are known to dominate over dispersion intermolecular forces and dipole-dipole intermolecular forces [2,5,[12][13][14]16,31,34,35,[40][41][42][43][44]. This is clear in the definition of specific interactions, given by Huyskens et al [16], ''specific interactions are short-range, site-bounded cohesion forces that considerably weaken a given chemical bond of one of the partners''.…”

The properties of a polymeric system are a consequence of the interactions that occur between the various components of these complex systems. These components may vary significantly in terms of chemical nature (e.g. organic/inorganic), physical properties (e.g. particle size, surface area, molecular weight), structural characteristics and proportion in the formulations composition. This review paper addresses the major approaches in use regarding the analysis of the interactions that occur between the polymeric system components and the use of such approaches in the interpretation of the chemical, physical and thermodynamic properties of these systems. Special attention is given to the technique of inverse gas chromatography.A case study is presented, where use was made of inverse gas chromatography to characterize thermodynamically the surface of the major components of pigmented PC/PBT blends. The concept of Lewis acidity/basicity was used in the interpretation of the intermolecular interactions nature and potential in these blends, as encountered in phase separation and phase preferences phenomena and as expressed in the morphology, the physical and the mechanical properties of these commercially important composites. #

A novel method has been developed to toughen phenolic resin using phenoxy resin. Phenoxy resin was dissolved in phenol to form a glutinous mixture at 110ЊC, and an acid catalyst ( p-toluene sulfonic acid, PTSA) was utilized to reduce the viscosity of mixture. The mixture was blended with resole-type phenolic resin.IR spectra confirmed that the amount and strength of hydrogen bonds increased with PTSA content, and the viscosity decreased with PTSA content in the polymer blends.The wet-out of glass fiber by modified resin was improved. The flexural and notched Izod impact strength of the polymer-blend composites increased significantly.
