Abstract
The present invention provides a method of improving the elastic modulus of oil while maintaining oil flowability. The elastic modulus of oil is significantly increased by the addition of polymers containing polyether groups. The treated oils are useful in products that require oils with both high elastic modulus and fluidity.
