Sever viscosity fluctuation resulted from temperature variation may impact negatively on the performance of lubricants. To prevent this from happening and to increase the viscosity index, below types of polymers are used:
♦ Polymethacrylate (PMA)
♦ Olefin Copolymers (OCP)
♦ Polyisobutene (PIB)
♦ Hydrogenated Styrene-Isoprene (SIP) The selection of appropriate polymer is significantly important as each polymer may behave in a unique way in terms of viscosity, viscosity index and shear stability.
