Single chain polymer nanoparticles as shearresilient

Since the intrinsic viscosity of a polymer solution relates to the molecular weight through the MarkHouwink equation, and since the VI depends on the size of the macromolecule [16, 17], the shear induced mechanochemistry of the VM macromolecules results in the doubly undesired decrease of both the thickening power and the VI of the lubricant.
