Time-Course Analysis of Polyvinyl Chloride Adhesive by FTIR

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 timecourse 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.
