Abstract:This paper is focused on the characterization and quantitative analysis of two polypropylene/calcium carbonate composites using fourier transform infrared spectrometry(FT-IR)and thermal gravity analysis(TGA).The additives are proved to be chemicals similar to a copolymer of styrene and maleic acid and stearic acid or its obtained from samples and the residues of chemically treated samples.A satisfied result of quantitative analysis of calcium carbonate,additives,and polypropylene in the composites was obtai...
