We investigated turbulent drag reduction induced by polyisobutylene molecules dissolved in kerosene and their chain degradation under a turbulent flow. Using a rotating disk apparatus, we found that drag reduction efficiency decreased with time due to mechanical degradation of the polyisobutylene molecules. The theoretical equation for molecular degradation based on midpoint scission in a turbulent flow was found to be well fitted to high concentration polymer solutions in a mildly turbulent flow.
