Scope
Main technical content: This document describes a method for determining the total ethylene content, the ethylene content in the rubber phase, and the rubber phase content in impact-resistant copolymer polypropylene (PPB) using Fourier transform infrared spectroscopy transmission. This document is suitable for impact-resistant copolymer polypropylene granules or powders with a total ethylene content of 2% to 12% (by mass) and an ethylene content in the rubber phase of 40% to 60% (by mass).
