About Polymer Structure Analysis

Many spectroscopic methods of analysis are used to answer the question: “What is it?”  Great polymer structure analysis requires that additives and fillers be removed.  Also, polymer blends need to be separated into individual fractions.  Then, end-groups, side-groups, co-monomer contents, and sequence distributions can be deduced.  Polymer Structure Analysis is useful in identifying new material suppliers, root causes for product failures, and product formulations in patent infringement cases.

  • Approaches

    At the simplest level, a polymer identification can be made using Fourier Transform Infrared (FTIR) Spectroscopy with a sample as small as the period in this sentence.

    When a client requires a high level of detail Nuclear Magnetic Resonance (NMR) Spectroscopy is applied in this case, typically carbon and proton NMR.  Silicon, fluorine, and phosphorus NMR spectra can also be acquired.

    In some cases, polymer structure analysis can be provided using X-Ray Photoelectron Spectroscopy (XPS), a particularly powerful technique for thin coatings and surface layers.

     

     

  • Sample Considerations

    The sample considerations can vary greatly depending on the purpose for which you require polymer structure analysis.  We encourage you to contact us with your needs and to discuss the testing protocol that will be suit your end goals.

     

  • Experience

    We have performed polymer structural analysis for a variety of purposes.  Some examples of the reasons our clients routinely need polymer structure analysis include: 

    • Critical comparison for patent claims
    • To evaluate misappropriation of trade secrets 
    • To assist with identifying additional material suppliers
    • For determining root cause of product failures.

    Products we've tested include:

    • Cosmetics
    • Impact resistant polymers
    • Bioabsorbable polymers
    • Epoxy compositions
