Butylene/Ethylene/Styrene Copolymer is a polymer of butylene and ethylene and styrene monomers terminated by hydrogenation Science: Functions: Viscosity Controlling Safety Ratings: CIR: Safe as used

CAS #

68648-89-5

Form

Liquid

Plant-Derived

Synthetic. Produced from butylene, ethylene, and styrene monomers derived from petroleum hydrocarbons. Synthesized through catalytic polymerization of the three monomers, followed by hydrogenation to saturate bonds.
