We provide unambiguous experimental evidence that ring polymers are stronger depleting agents in colloidal suspensions than their linear counterparts. We use an intermediate volume fraction (ϕ_{c}=0.44) colloidal gel based on the classic poly(methyl

Reversible-deactivation radical polymerization (RDRP) based on direct photolysis has a favorable reaction structure for superior controllability compared to that of conventional RDRP. However, this aspect has not been fully demonstrated because the p

Adding small amounts of ring polymers to a matrix of their linear counterparts is known to increase the zero-shear-rate viscosity because of linear-ring threading. Uniaxial extensional rheology measurements show that, unlike its pure linear and ring
