S3–23 Specification for oxidised polyethylene
(1) In this section:
ASTM refers to standard test methods prepared by the American Society for Testing and Materials.
CAS means the Chemical Abstracts Service (CAS) Registry Number.
oxidised polyethylene (CAS 68441-17-8) is the polymer produced by the mild air oxidation of polyethylene.
(2) For oxidised polyethylene, the specifications are the following:
(a) average molecular weight—min 1200 (osmometric);
(b) viscosity at 125°C—min 200cP;
(c) oxygen content—max 9.1%;
(d) acid value—max 70 mgKOH/g (ASTM D 1386);
(e) drop point—min 95°C (ASTM D 566);
(f) density (20°C)—0.93-1.05 g/cm³ (ASTM D 1298, D 1505);
(g) extractable constituents:
(i) in water—maximum 1.5%; and
(ii) in 10% ethanol—max 2.3%; and
(iii) in 3% acetic acid—max 1.8%; and
(iv) in n-pentane—max 26.0%.
Note Extraction of oxidised polyethylene—25.0 g of finely ground oxidised polyethylene powder (particle size 300–1 000 μm) is extracted for 5 hours in the Soxhlet apparatus with 350 mL of solvent. The solvent is then distilled off and the distillation residue is dried in a vacuum oven at 80–90°C. After weighing the obtained residue, the components soluble in the solvent are calculated in % weight (based on the initial weight used).
S3–24 Specification for phytosterols, phytostanols and their esters
(1) Subject to subsections (2) and (3), phytosterols, phytostanols and their esters must comply with a monograph
