3,4-divinylbenzyl trithiocarbonate (DVBTC) was successfully synthesized via a one-pot reaction and used as a dual chain transfer and crosslinking agent to prepare poly(n-butyl acrylate) (PBA) networks at target crosslink densities from 1.5 to 307.8mol/m<sup>3</sup> via reversible addition fragmentation chain transfer (RAFT) polymerization. The cross-link density of PBAs were measured by swelling and through the Flory-Rehner equation and oscillatory shear rheology from the plateau modulus. A monotonic increase in the crosslink density with RAFT agent concentration was observed. The role of interchain radical transfer during crosslinking to produce branched chains and more complex viscoelastic behavior will be discussed.
