This test method is used to determine if there is any heavy material in the butadiene. It is possible that these materials could be deleterious to a polymerization reaction.

1.1 This test method covers the determination of nonvolatile material in polymerization-grade butadiene.

1.2 The values stated in SI units are to be regarded as standard. The values stated in inch-pound units are for information only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
