标准摘要
[中文适用范围]： 本国际标准规定了通过“悬浮”、“本体”和“乳液”聚合工艺制备的优选自由流动的氯乙烯均聚物和共聚物树脂的筛分保留和粒度分布的测定方法。 控制这些特性有助于确保供应的一致性和可预测的加工行为。 [外文原描述]： ISO 4610:2001 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.
英文名称Plastics — Vinyl chloride homopolymer and copolymer resins — Sieve analysis using air-jet sieve apparatus
