| titleOfInvention | A new method for detecting the deterioration of vinyl monomers |
| abstract | The invention relates to a new method for detecting whether vinyl monomers are deteriorated. Its technical scheme is: including the following process, in mass percentage: first, the vinyl monomer is configured into a solution with a concentration of 10%-50%, and then an initiator with a concentration of 0.1%-1% is added to cause a polymerization reaction to occur , use the detection device to collect the heat generation in the whole reaction process, and determine whether the sample has deteriorated by comparing the temperature change curves of the standard sample and the sample to be tested; Heat will be released during the reaction, which is the characteristic of the polymerization reaction. The present invention utilizes that the exothermic heat of the polymerization reaction will be reduced after the ethylene-based monomer self-polymerizes and deteriorates. By comparing the reaction exotherm of the standard sample and the test sample to detect whether the sample has deteriorated The detection equipment of the invention has simple structure, low manufacturing technology threshold, cheap equipment, and easy popularization. The detection method of the invention has simple operation and high detection accuracy. |
