Chemicals
Polymeric materials may undergo changes in composition or molecular structure due to such factors as mixing, heating, light exposure, etc. These changes may reach completion within a few seconds or may progress slowly over several hours. An FTIR is useful for conducting analysis of polymer composition and molecular structure, and LabsolutionsIR software, with its included time- course measurement program, permits tracking of sample peak changes over time. Although the program is suitable for tracking a gradual reaction, the included Rapid Scan feature is effective in cases where the sample reaction is completed within a few seconds. Here, we introduce an example of measurement of the curing process of polyvinyl chloride resin adhesive using the time-course measurement program.
