ELASTOMER COMPOSITIONS COMPRISING GAS-TO-LIQUID BASE OILS AND PROCESSES FOR PREPARATION THEREOF

摘要

Elastomer compositions comprising a gas-to-liquid (GTL) derived synthetic base oil as an extender oil are provides, wherein the base oil has not been subjected to a process for the removal of haze causing components and wherein the synthetic base oil comprises at least 80 wt. % of compounds having at least 30 carbon atoms. Elastomers described include those comprising one elastomer component, such as a rubber, and a base oil wherein the base oil has not been treated to remove haze components and is present in the range of from 0.1 wt% to 50 wt% based on the weight of the total elastomer composition. The haze components may include paraffinic microcrystalline wax formed as part of the GTL process.
