  3. what is the degree of acetylation and purity of the PVB? Density and molecular weight of the PVB?

    1 answer

    1. The only quality control testing performed for product P110010 is for appearance and viscosity. There is no testing performed on a lot-to-lot basis for density, purity, degree of acetylation, or molecular weight.
      The website does state that "Polyvinyl butyral resin similar to Butvar® B-98 for thin film support in electron microscopy."

      For Butvar B-98 the following information is available:
      Butvar® B-98 has the following characteristics (see https://productcatalog.eastman.com/tds/ProdDatasheet.aspx?product=71095422&pn=Butvar+-+B-98#_ga=2.208860571.827911750.1655887049-264082885.1655887049):
      - Molecular weight: 40,000 - 70,000 (Size exclusion chromatography with low angle laser light scattering standard)
      - % of hydroxyl content (as PV alcohol): 18.0 - 20.0%
      - % of acetate content (as PV acetate): 2.5% maximum
