I'm a student in the last class of the series of general chemistry at my university. For our last lab we got to use an FT-IR spectroscopy machine to scan three different polymers and an everyday object (polymer) of our choice. I brought in this stuff called APT-II Porcelain and Stoneware Enhancer, which is kind of like a glue for unfired pottery (I'm a potter in my spare time). So I scanned it and the graph came out crazy. The graph can be seen below. Can anyone tell me what this chemical is? When my TA looked at it she was very confused. The bottle did say it's an acrylic emulsion additive, but I really have no clue what that is. I also need to know the exact chemical model of it, or at least a pretty good guess of it. Can any of you guys give it a shot?
