Polybutene-1 | Technical Info

Polybutene is a polyolefin and exists in two isomeric forms depending on where the carbon double bond is positioned in the monomer molecule. If it is between the first and second carbon atoms in a linear molecule (Butene-1), then the chemically accurate name of the resulting polymer is Polybutene-1 (PB-1). If it is a branched monomer molecule (Polyisobutene) then the resulting polymer is called Polyisobutene (PIB).
