Scope

This document describes the method of determining the content of polybutylene terephthalate/adipate/butyrate (PBAT), polybutylene succinate (PBS), and polylactic acid (PLA) in plastics using nuclear magnetic resonance spectrometers and high-performance liquid chromatographs. This document is applicable to plastic products made from polybutylene terephthalate/adipate/butyrate (PBAT), polybutylene succinate (PBS), and polylactic acid (PLA) as raw materials, which are processed by mixing one or several of these raw materials together with inorganic components and/or additives.
