This International Standard specifies a method for the determination of the sieve retention and particle size distribution of preferably free-flowing vinyl chloride homopolymer and copolymer resins prepared by the “suspension”, “bulk” and “emulsion” polymerization processes. Control of these characteristics can help to ensure consistency of supply and predictable processing behaviour.
