Abstract
Viscosity index modifiers are added to oil-extended, flame-retarded rubber to increase the flash point of the extending oil and enhance the effects of the flame retardant and thereby lower the flammability of the rubber composition. The modifiers have an aliphatic non-polar backbone containing pendant carboxyl groups.
