Digital light processing 3D printing of modified liquid isoprene rubber using thiol-click chemistry.

ABSTRACT: This study highlights the additive manufacturing of diene-rubbers with digital light processing (DLP). The network formation relies on the crosslinking of a methacrylate-functional liquid isoprene rubber via photo-induced thiol-click chemistry. Bi-functional divinyl ethers are added as reactive diluents, which benefit from a low potential for skin irradiation and skin sensitization. Along with significantly reducing the viscosity, the divinyl ethers accelerate the cure kinetics of the diene-rubber across the main chain C[double bond, length as m-dash]C bonds of the isoprene units. Photo-DSC measurements reveal that the length of the glycol-spacer and the chemical structure (glycol versus alkyl) of the divinyl ether influence the photo-reactivity of the rubber formulations in
