Research Abstract

In this study, in order to develop novel water-soluble super lubrication system, new water-soluble branched polymers such as hyperbranced polymerｓ were synthesized, and the relationship between polymer structure and viscosity was discussed. The obtained polymers in water showed very lowviscosity, therefore, the solution was useful as water-soluble lubricant agent. The lubrication property is due to the globular structure of the polymer in water.
