Scope
Scope: This document specifies the classification, technical requirements, test methods, inspection rules, and marking, packaging, transportation, storage, and handling of cis-polybutadiene rubber (NdBR) synthesized by rare earth catalytic systems (referred to as rare earth cis-butadiene rubber). This document applies to rare earth cis-butadiene rubber obtained by coordination polymerization using butadiene as the polymerization monomer and rare earth complexes as the catalyst.
