Results indicated that increasing extrusion temperature from 190 C to 195 C produced significant physical changes in ABS blends. There is a breakdown of styrene acrylonitrile and butadiene...

2015年7月3日 · ABS plastics are heterogeneous blends of styrene-acrylonitrile copolymers and modified polybutadiene rubbers. The degree of toughness of these versatile thermoplastics is almost entirely a function of the type and character of the rubber.

FTIR spectrum of ABS is characterized by many absorption peaks, such as, 2234 cm -1 and 1452 cm -1 , as shown in Fig. 2e. These bands are attributed to nitrile group in ABS, i.e., C≡N and...

FTIR spectrum from sample 7 showing peaks from ABS (at 698.26, 758.05, 910.44, 965.41, 1028.10, 1452.46 and 1492.96 cm − 1 ) as a majority with traces of polycarbonate (at 1015.56, 1070.53,...

2022年6月22日 · The characterization of grafting properties of ABS latexes using NMR spectroscopy has been for the first time performed in this work. In order to obtain the contributions of all the polymer fractions that form the ABS polymer, suitable conditions have been found for both solid-state and liquid-state NMR experiments.

2017年9月5日 · Fourier Transform Infrared Spectroscopy (FTIR) is adopted to study the aging characteristics of poly (acrylonitrile–butadiene–styrene)/polycarbonate (ABS/PC) blend under UV-irradiation in air by analyzing the variation of the three main absorbance at about 967 cm − 1, 1720 cm − 1 and 3420 cm − 1 associated with carbon-hydrogen bonds belonging to...

FTIR spectrum of ABS is characterized by many absorption peaks, such as, 2234 cm-1 and 1452 cm , as shown in Fig. 2e. These bands are attributed to nitrile group in ABS, i.e., C≡N and double bonds of butadiene blocks. The absorption at 1677 and 1495 cm-1 are related to styrene double bonds in ABS terpolymer.

由于丁二烯-苯乙烯-丙烯腈接枝聚合物 (ABS)中橡胶的含量较高,是一种典型的核壳结构,采用溴化钾 (KBr)压片法制备的样品,研磨后不均匀,进行透射法测试效果不理想.而选用傅里叶变换衰减全反射红外光谱法 (ATR-FTIR)在样品制备方面,检测无损伤方面以及获取表面信息等等都具有特殊优势,本文主要利用ATR-FTIR法优势,研究了不同橡胶含量的ABS粉料红外光谱分析过程中聚丁二烯结构及组成的定性定量分析,并将丁二烯结构及组成的分析结果与材料的力学性能相对应.使用该方法具 …

The fast identification and accurate characterization of acrylonitrile-butadienestyrene (ABS) terpolymers by computer aided Fourier transform infrared spectroscopy is described. Samples are prepared as films from chloroform suspensions and identified by a library search routine after FTIR measurement.

For ABS with 5% MA and 0.5% DCP, an efficiency of 62% was reached with the degree of grafting 3.1% MA. FTIR spectra confirmed new band in ABS chain in 1780 cm−1 due to the carbonyl group.
