Identifying Polymers

No view

In this experiment solutions with known densities are used to identify the polymers used in everyday materials. This is an experiment from the Practical Chemistry project, developed by the Nuffield Foundation and the Royal Society of Chemistry. Samples of several polymers found as .Identifying polymers. Topic. Polymers. Timing. 45 min. Description. The students place samples of plastic into solutions of known density to identify the polymers. Apparatus and equipment per group w Six test-.s w Test-rack w Glrod w Samples of seven different plastics. Chemicals per group w Solutions 1-6 .Identification of polymer and plastic materials,isting your product development, materials selection, identification and reverse engineering. Expert polymer and plastic identification testing is required during polymer product development, compe.iveysis, reverse engineering, deformulation, layer identification, .Most of the polymers we encounter in our daily lives are the six polymers listed in Table 1. To make recycling of these polymers easier, the plastics industry has adopted the codes shown. Since compliance in labeling is voluntary, not all plastics are labeled for identification. Identification, simply by appearance, is difficult .

The term "polymer" describes cl.es of molecules with large numbers of repeating structural units connected through covalent bonds. The major identifying feature .Water based acrylic polymers for graphic arts, paint additives, and industrial coatings. Stain resistant cationic polymers for primers..Molecularly imprinted polymers for separating and sensing of macromolecular compounds and microorganisms.Molecular identification of polymers and anthropogenic particles extracted from oceanic water and fish stomach - A Raman micro-spectroscopy study.
