“…The main problem that appears when polymer blends are prepared from two immiscible and non compatible polymers is strong phase separation due to weak adhesion resulting in poor properties of blends [1][2][3][4][5]. A huge number of interesting questions are connected with the general subject of polymer interfaces.…”

A series of various types (different structures) of ethylene-polypropylene-diene-graft-polystyrene (EPDM-g-PS) copolymers were synthesized and their surface property variations were studied using surface analysis techniques such as surface contact angle measurement. Pre-synthesized graft copolymers were added (5 phr) in styrene-acrylonitrile (SAN)/ethylene-propylene-diene (EPDM) blends composition of 95/5 and 90/10. The adhesion parameters at the interface, that is work of adhesion, the interfacial energy and the coefficient of wetting were calculated and correlated to the differential scanning measurements measurements and SEM micrographs in order to study the effect of graft copolymers on compatibility of SAN/EPDM blends. It is obvious that depending of the graft copolymer's structure, various interactions between the components in the blend will be established, resulting in better adhesion which implicates improvement of compatibility in blends. Also, from the results, it can be seen that differences in structures of the added compatibilizer are clearly reflected in the adhesion parameters results, making this an acceptable method to determine whether two polymers are compatible. Morphology of the blends with the graft copolymers is significantly finer and the dispersed size is more uniformly distributed in comparison to the neat SAN/EPDM blend. The conditions of the optimal adhesion parameters with compatibilizer location at the interface, predicting by the thermodynamical models, correlated well with the improvement of the morphology and thermal measurements.

“…Some of them are processing conditions [14][15][16], viscosity or viscosity ratio [17,18], blend composition [13,19], shear intensity [20], interfacial tension [21,22], interfacial behaviors [23], compatibilizers (e.g. block copolymers [24][25][26][27][28] or graft copolymer [29][30][31][32][33][34][35], and inorganic nanoparticles such as nanoclay [12,36,37] and carbon nanotubes [38,39]). For immiscible polymer pairs, adding premade copolymers as compatibilizers is an effective way to reduce the interfacial tension [21,40].…”

“…Therefore, in most cases, a number of the copolymer molecules prefer to form micelles [11–13] in the blends rather than locate at the interface, consequently, the compatibilization efficiency is low. Another way to improve the interfacial adhesion is in situ reactive compatibilization [14–30]. When two polymer chains with reactive functional groups meet at the interface during melt blending, they can react to form block or graft copolymers, which can reduce interfacial tension and stabilize the morphology of the blend.…”

Polymer blending is a common and effective way to develop new materials with desirable physical and mechanical properties. Since most polymer pairs are immiscible, reactive compatibilization has been extensively studied to stabilize morphology of polymer blends and improve their mechanical properties. In the past several years, considerable interest has been expressed in understanding the fundamental kinetics and mechanisms of the interfacial reaction, investigating the reinforcement of the interfacial adhesion and the development of morphological structure at polymer-polymer interface induced by the interfacial reaction. The present review focused on some theoretical and experimental results that include the formation and growth of copolymers at the interface, and also the major factors such as reaction conditions, the concentration and bulk properties of the functionalized polymer, the thermodynamic interaction between the functionalized polymer and the matrix, which can influence the interfacial adhesion and morphological development.
