A new ASTM International standard determines polymer content in alpha-methylstyrene (AMS), a raw material used in the production of a variety of consumer products.

AMS manufacturers and those who use AMS as a raw material will be the primary beneficiaries of the new standard (soon to be published as D7977, Test Method for Polymer Content of a-Methylstyrene (AMS)). In addition, third party laboratories will find D7977 useful for quality verification during material transfers and shipping.

AMS is used to create adhesives for such products as diapers and boxes. In addition, AMS is an ingredient in some resins used to help make cars and airplanes. Previously, AMS was covered under a separate ASTM standard for polymer content in styrene. ASTM Subcommittee D16.07 (Styrene, Ethylbenzene and C9 and C10 Aromatic Hydrocarbons) determined that a separate standard was needed for AMS.

This standard will soon be available for purchase at www.astm.org, or contact ASTM Customer Relations (tel +1.877.909.ASTM; sales@astm.org). ASTM welcomes participation in the development of its standards. Become a member at www.astm.org/JOIN.
