“…Several researchers [3][4][5][6][7][8][9] have investigated effects of blend ratio and compatibilisation on the dynamic mechanical properties. Al-Malaika and Kong [10] studied the compatibilisation of functionalised EPR with GMA. Examination of the DMA of the reactive and physically compatibilized blends shows a smaller separation between the glass transition temperatures.…”

Abstract. The dynamic mechanical properties such as storage modulus, loss modulus and damping properties of blends of nylon copolymer (PA6,66) with ethylene propylene diene (EPDM) rubber was investigated with special reference to the effect of blend ratio and compatibilisation over a temperature range -100°C to 150°C at different frequencies. The effect of change in the composition of the polymer blends on tanδ was studied to understand the extent of polymer miscibility and damping characteristics. The loss tangent curve of the blends exhibited two transition peaks, corresponding to the glass transition temperature (Tg) of individual components indicating incompatibility of the blend systems. The morphology of the blends has been examined by using scanning electron microscopy. The Arrhenius relationship was used to calculate the activation energy for the glass transition of the blends. Finally, attempts have been made to compare the experimental data with theoretical models.

“…5 In this work, the mixed solvent of phenol/tetrachloroethane/xylene (40/40/20 w/w/v) was first prepared by mixing phenol (40 part by weight) and tetrachloroethane (40 parts by weight) using a stirring rod at room temperature. The last component, xylene (20 parts by volume) was then incorporated into the mixture and continuously stirred for at least 30 min.…”

“…The epoxy functionalized acrylate rubber (ACM) has been one of the successful examples. 8−10 Other types of epoxy-functionalized rubbers include glycidylmethacrylate-grafted ethylene propylene diene monomer EPDM (EPDM-g-GMA), [4][5][6]11 poly(ethylene-co-ethyl acrylate) (PEEA), 12 and epoxidized natural rubber (ENR). 13 Compatibilization of polymer blends has been typically characterized by dynamic mechanical analysis (DMA) in terms of viscoelastic properties (e.g., storage modulus and loss modulus, or tan δ).…”

A simple blend (i.e., blend without curative) of 60/40 rubber/nylon-12 with three different types of natural rubber (i.e., air-dried sheet natural rubber (ADS) and epoxidized natural rubbers (ENR) with 25 and 50 mol% epoxide) was prepared by the melt-mixing process. Influence of different types of PROPERTIES OF EPOXIDIZED NATURAL RUBBER AND NYLON-12 BLENDSrubbers and the level of epoxide groups in ENR molecules on the properties of the blends were investigated. It was found that all the blends exhibited a co-continuous phase morphology. Furthermore, the ENR/nylon-12 blends exhibited superior mechanical properties, stress relaxation behavior, thermal and rheological properties, and a finer grain morphology than that of the ADS/nylon-12 blend. This may be attributed to the higher interfacial adhesion between the ENR and nylon-12 phases via a chemical interaction of epoxide groups in ENR molecules and polar functional groups in the nylon-12 molecules. Temperature scanning stress relaxation (TSSR) measurement was also performed. Improvement in stress relaxation and thermal resistance of the blends with ENR was observed. Moreover, the higher temperature coefficient and lower glass transition temperature (T g ) of the nylon-12 phase in the ENR-50/nylon-12 blends were found. C 2011 Wiley Periodicals, Inc.

“…have been photografted onto several polymeric materials surfaces to improve their wettability, adhesion, biocompatibility, and glycidyl methacrylate (GMA) is one of the commonly used monomers. The melt grafting or reactive extrusion grafting of GMA onto polymeric materials has been extensively studied to improve the compatibility of polymer blends [13,14]. The grafting of GMA onto polymeric materials can also be initiated by several other ways, such as chemical (peroxide) [15], high-energy irradiation [16] and photo or UV-induced initiation [17].…”
