Polyvinyl acetate is a thermoplastic polymer, represented by the formula: (C4H6O2 )n in which the value of n lies between approximately 100 and 17,000.IDENTIFICATION
IMPURITIES
A. Procedure:
Sample: 100 mg of Polyvinyl Acetate
Analysis: Dissolve the Sample in 2.5 mL of acetone, place two drops on a potassium bromide plate, and dry to evaporate the solvent.
Acceptance criteria: IR absorption spectrum.
B. Procedure:
Sample: 0.5 g of Polyvinyl Acetate
Analysis: Saponify the Sample in a mixture of 25.0 mL of 0.5 N alcoholic potassium hydroxide and 25.0 mL of water.
Acceptance criteria: The solution so obtained meets the requirements of the tests for Acetate.
Residue on Ignition: NMT 0.1%
Residual Peroxides:
Sample: 0.85 g of Polyvinyl Acetate
Analysis: Place the Sample in a borosilicate glass flask with a ground-glass neck. Add 10.0 mL of ethyl acetate, and heat under a reflux condenser with constant agitation. Allow to cool. Replace the air in the container with oxygen-free nitrogen and add a solution of 1.0 mL of glacial acetic acid and 0.5 g of sodium iodide in 40.0 mL of water. Shake thoroughly and allow to stand protected from light for 20 min. Titrate with 0.005 N sodium thiosulfate until the yellow color is discharged. Perform a blank titration.
Acceptance criteria: The difference between the titration volumes is not greater than 1.0 mL; and NMT 100 ppm, calculated as hydrogen peroxide, is found.
Limit of Vinyl Acetate: To pass the test.
Fats and Fixed Oils: To pass the test --- The acid value is NMT 0.5.
Fats and Fixed Oils: To pass the test --- The ester value, calculated from the Saponification Value and the Acid Value, is between 615 and 675.
Loss on Drying: Dry 1.5 g at 100C for 2 h in a vacuum: it loses NMT 1.0% of its weight.
Average Molecular Weight and Molecular Weight Distribution: To pass the test --- The values of weight-average molecular weight and polydispersity are, respectively, NLT 85% and NMT 115% of their respective values as stated on the label.
Polyvinyl Acetate FCC Food Grade Specifications
CAS 9003-20-7DESCRIPTION
Polyvinyl Acetate occurs as a clear, water white to pale yellow, solid resin. It is prepared by the polymerization of vinyl acetate. After completion of polymerization, the resin is freed of traces of residual catalyst (usually a peroxide), monomer, and/or solvent by vacuum drying, steam sparging, washing, or any combination of these treatments. The resin is soluble in acetone, but it is insoluble in water.REQUIREMENTS
Identification: The infrared absorption spectrum of a melted sample on a potassium bromide plate exhibits relative maxima at the same wavelengths as those of a typical spectrum as shown in the section on Infrared Spectra, using the same test conditions as specified therein.
Free Acetic Acid: Not more than 0.05%.
Lead: Not more than 3 mg/kg.
Loss on Drying: Not more than 1.0%.
Molecular Weight: Not less than 2000.We also supply Tween Polyvinyl Acetate BP Ph Eur Grade.
