DEFINITION 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 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. IMPURITIES 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. Specifications of Poly(vinyl acetate) BP Ph Eur Grade Ph Eur DEFINITION Poly(vinyl acetate) is a thermoplastic polymer obtained by polymerisation of vinyl acetate using a suitable starter, without solvent or with water or 2-propanol. The vast majority of the acetate moieties are attached to non-neighbouring carbon atoms of the chain. The index n is about 100 - 17 000. The relative molecular mass lies between 10 000 and 1500 000. The viscosity is 4 to 250 mPas. The ester value, which characterises the degree of hydrolysis, is 615 to 675. CHARACTERS Appearance: White or almost white powder or colourless granules or beads. Solubility: Practically insoluble in water, freely soluble in ethyl acetate, soluble in alcohol. It is hygroscopic and swells in water. It softens at temperatures above 40-50C. IDENTIFICATION A. Infrared absorption spectrophotometry. To pass the test. B. It complies with the test for viscosity (see Tests). C. Saponify 0.500 g in a mixture of 25.0 ml of 0.5 M alcoholic potassium hydroxide and25.0 ml of water. The solution obtained gives the reaction of acetates. TESTS Solution S: Suspend 50.0 g in 100 ml of ethyl acetate R in a borosilicate glass flask with a ground-glass neck. Heat under a reflux condenser with constant stirring for 30 min. Allow to cool. Filter through a tared sintered glass filter (16) (2.1.2) and wash the residue with 50.0 ml of ethyl acetate, pour the filtrate into a 250 ml graduated flask. Dilute to 250 ml with ethyl acetate. Appearance of solution: Solution S is clear and colourless. Viscosity: 85 per cent to 115 per cent of the value stated on the label. Determine the viscosity immediately after preparation of solution S at 20± 0.1C by using a rolling ball viscosimeter. Acid value: Maximum 2.0, determined on 5.0 g dissolved in 50 ml of alcohol by shaking for 3 h. Ester value: 615 to 675. Saponify 0.500 g in a mixture of 25.0 ml of 0.5 M alcoholic potassium hydroxide and 25.0 ml of water. Residual peroxides: Maximum 100 ppm, calculated as hydrogen peroxide. Vinyl acetate: maximum 0.3 per cent to meet the test. Heavy metals: Maximum 10 ppm. Loss on drying: Maximum 1.0 per cent, determined on 1.000 g by drying in an oven at 105C. Sulphated ash: Maximum 0.1 per cent, determined on 1.0 g. Specifications of Polyvinyl Acetate FCC Food Grade CAS 9003-20-7 DESCRIPTION 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.
