Method and device for measuring the content of ethylene-propylene rubber in impact polypropylene copolymer

摘要

The present invention relates to a method and a measuring device for measuring the content of ethylene-propylene rubber in an impact polypropylene copolymer. According to the present invention, the preparation of a sample is simple and can be measured within up to 4 hours including pretreatment, and rheological properties Simultaneously with the measurement, the ethylene-propylene rubber content in the impact polypropylene can be calculated. In addition, since a separate solvent is not used, it is harmless to the human body, and expertise in analysis is not required, and accurate measurement is possible regardless of the shape of the measurement sample.
