“…As a result, the activation energy of this experiment is 48.6881 kcal mol À1 , which is determined by averaging 48.6338 and 48.7384 kcal mol À1 . This result is in agreement with that reported by Polli et al (2009), who calculated an activation energy of 48 kcal mol À1 by applying the Vyazovkin approach, in a non-isothermal method, under N 2 atmosphere, and heating rates 0.5, 1, 2, 5 and 10 C min À1 . The other activation energy values of ABS reported in the literature are listed in Table 3.…”

This article proposes a new logarithmic approximate formula of the Arrhenius temperature integral p(u) for nonisothermal analysis using the Solver algorithm. The proposed formula is presented as À ln pðuÞ ¼ a þ b ln u þ cu, and the values for a, b and c are 0.69038, 1.71975 and 1.01249, respectively, for 1 u 5 20; 0.45891, 1.85919 and 1.00275, respectively, for 20 u 5 35; and 0.27341, 1.93235 and 1.00060, respectively, for 35 u 5 100: The validity of the proposed Arrhenius temperature integral formula has been tested by investigating the thermal decomposition kinetics of acrylonitrile-butadiene-styrene (ABS). The activation energy and the pre-exponential factor determined by the proposed formula are 48.7385 kcal mol À1 and 2.6 Â 10 16 s À1 , respectively. The reaction model of ABS thermal decomposition obtained with the method of master plots indicates that the phase boundary reaction model best describes the thermal decomposition reaction of ABS. The accuracy of the proposed Arrhenius temperature integral formula has also been tested by numerical analysis, and deviations from numerical values were compared with those of several previously published approximation formulae. The results show that the proposed formula is superior and is nearly ideal for estimating kinetic parameters from non-isothermal thermogravimetric data.

“…So, a better understanding of its fundamental properties is essential. There have been several reports on the thermal analysis of ABS (Day et al 1995, Yang et al 2004, Balart et al 2006, Polli et al 2009, Wang and Cai 2012.…”

“…. The TGA curve of ABS display characteristic single‐stage degradation behavior and it showed onset temperature ( T onset ) and degradation temperature ( T d ) at 365°C and 385°C, respectively (Table ). The single‐stage degradation includes the decomposition reaction of PB and styrene components.…”

The Izod impact strength of maleic anhydride-grafted acrylonitrile butadiene styrene (MA-g-ABS) copolymer has been improved by the use of rubbery poly(ethyleneco-vinyl acetate) (EVA). The MA-g-ABS is prepared by an internal mixer using dicumyl peroxide as free radical initiator, and the grafting degree was determined using back-titration method. The amount of EVA is optimized by evaluating the Izod impact strength, tensile, and flexural properties of the samples. Addition of 6% EVA into MA-g-ABS system improved the Izod impact strength and tensile strength by 18% and 35%, respectively. The miscibility of EVA in ABS and MA-g-ABS matrices has been observed using differential scanning calorimetry and scanning electron microscopy techniques. The enhanced adhesion property exhibited by MA-g-ABS/ EVA systems promises it as a good candidate for thermoplastic coating applications on aluminum substrates.

“…It is also possible to enhance mechanical properties such as tensile strength, hardness and flexural modulus of ABS using fibre-reinforcement. This polymeric material has various application as in the architecture, construction, computer and business equipment, personal care products, toys, medical devices and in automotive interior components [1][2][3].…”

“…They also found out that ABS HH is a little more thermally resistant than ABS HI and much more than ABS GP because of its highest acrylonitrile content. ABS HI and ABS HH also exibit high activation energy because of high butadiene content, this is probably because the SAN matrix is directly bonded to butadiene and the liberation of butadiene is very difficult during the degradation reaction [1].…”

Abstract. This study deals with acrylonitrile-butadiene-styrene (ABS) which was subjected the drop-weight test before and after temperature and humidity load. ABS is an engineering plastic and also an important engineering terpolymer, which has butadiene part uniformly distributed through the acrylonitrile-styrene matrix and is commonly used in production of automotive interior components. The injection moulded ABS samples were subjected the penetration test at fall height 100 J before and after temperature and humidity load and the results were subsequently evaluated and discussed. It was found out that ABS after temperature and humidity load has lower impact resistance.
