BUNA-N and BUNA-S are polymers

BUNA-N monomers are 1,3-butadiene and acrylonitrile

★ It is also called as Nitrile-Butadiene-Rubber. It is a copolymer of butadiene and acrylonitrile

★ Cyanide ion in acryl group enhances the oil and solvent resistance hence the oil resistance is determined by the amount of acrylonitrile

★ it is used in seals, belts, oil seals etc and also used for making synthetic leather and footwear

★ It is a commercial name for NBR

BUNA-S monomers are 1.3-butadiene and styrene

★ It is also called Styrene-Butadiene Rubber

★ It has slightly less tensile strength than natural rubber

★ it is used for making automobile tyre and rubber soles

★ its commercial name is SBR
