“…20 Although rubber content has a serious effect in toughening mechanism of semicrystalline polymers, there are many other parameters that could influence the impact strength in the prepared blends. During melt blending in the extruder barrel, SEBS-g-MA was broken and dispersed in PA-6,6 matrix.…”

ABSTRACT:The toughening of glass fiber reinforced nylon-6,6 (PA-6,6) by using the functionalized triblock copolymer styrene-(ethylene-co-butylene)-styrene, grafted with maleic anhydride (SEBS-g-MA) was examined. Blends containing 2.5, 5, 7.5, 10, and 12.5 wt% copolymer were prepared by melt blending in a single-screw extruder. Emphasis was given to the study of mechanical properties in comparison with morphology and thermal properties of the aforementioned samples. Although the amount of SEBS-g-MA that was added in PA-6,6 was not enough to produce a super-tough material, a significant increase in the resistance to crack propagation and impact strength was observed in all blends. This behavior was proportional to the amount of SEBS-g-MA that was added for samples having up to 10%, rubber, while additional amounts seem to have no further effect. A small decrease in tensile strength was also observed. From FTIR spectroscopy and DSC analysis it was shown that the grafting extent of SEBS-g-MA to PA-6,6 was very low.

“…The rubber content employed was between 0 and 40 wt%. The Young's modulus and the yield stress decreased linearly with the increasing of the rubber content [9]. Every year, numerous papers are published on the recycling of rubber, where the waste rubber is used as a filler or it is blended with virgin rubber, but there are few publications discussing the influence of RR with a specific particle size in the properties of recycled blends.…”

Effect of the Recycled Rubber on the Properties of Recycled Rubber/Recycled Polypropylene Blends

“…Vulcanized EPDM shows some interesting properties, such as ozone, heat, light, weathering and chemical resistance [4]. The EPDM blends have also been extensively studied, dealing with the synthesis, characterization and applications of these systems and their nanocomposites [5][6][7][8][9][10][11]. Moreover, it has been reported that the ethylene content influences the properties of the EPDM polymers [12], and that a higher ethylene content gives more green strength (high elongation in the uncured state), poorer low temperature properties, imparts a more crystalline nature to the EPDM and increases its glass transition temperature.…”

The thermal degradation kinetics of several ethylene-propylene copolymers (EPM) and ethylene-propylene-diene terpolymers (EPDM), with different chemical compositions, have been studied by means of the Combined Kinetic Analysis. Until now, attempts to establish the kinetic model for the process have been unsuccessful and previous reports suggest that a model other than a conventional nth order might be responsible. Here, a random scission kinetic model, based on the breakage and evaporation of cleavaged fragments, is found to describe the degradation of all compositions studied. The suitability of the kinetic parameters resulting from the analysis has been asserted by successfully reconstructing the experimental curves. Additionally, it has been shown that the activation energy for the pyrolysis of the EPM copolymers decreases by increasing the propylene content. An explanation for this behavior is given. A low dependence of the EPDM chemical composition on the activation energy for the pyrolysis has been reported, although the thermal stability is influenced by the composition of the diene used.
