Abstract
A method for detecting a polymerization rate, wherein a polymer composition in a polymerization reaction process is sampled out and can be measured, and is separated into a volatile component and a non-volatile component, and the polymerization rate of the polymer composition is determined using the measured amount of the volatile component and/or non-volatile component, and also possibly the measured amount of the sample. Such method is best suited for detecting the rate of polymerization of polymer compositions. This enables proper quality control of the polymer composition in the polymerization reaction process.
