Description

technical field [0001] The invention relates to a low-odor styrene-acrylonitrile copolymer, and more particularly relates to preparing a low-odor styrene-acrylonitrile copolymer by adding an odor inhibitor that can effectively suppress the unpleasant smell in polypropylene composite materials. Acrylonitrile copolymer. The invention also relates to a method for preparing the composite material. Background technique [0002] Styrene acrylonitrile copolymer, namely ABS (acrylnitrole-butadiene-styrene copolymer), is a copolymer of acrylonitrile-butadiene-styrene, which is the most developed and changed variety among styrene series resins. Due to the advanced performance Compared with other resins, ABS has undoubted advantages and competitiveness due to its relatively low price. Therefore, ABS with various characteristics has been continuously developed and applied, which makes ABS the most widely used variety in engineering plastics. It is used in the automobile industry, hous...
