SSBR
ESBR
SBR is divided into emulsion styrene butadiene rubber and soluble styrene butadiene rubber according to the production process, emulsion styrene butadiene rubber ESBR is a polymer made of butadiene and styrene through emulsion polymerisation, which is free radical polymerisation; soluble styrene butadiene rubber SSBR is a copolymer made of butadiene and styrene in hydrocarbon solvents using lithium organolithium to trigger anionic polymerisation, which belongs to the anionic reactive polymerisation.
