Abstract
If the pressure sensitive adhesive is coated on the back, it can be used for bonding electronic tag, overburden, protective layer, and RFID layer. The acrylate pressure sensitive adhesives are simple and less pollution, so more and more companies pay attention on this kind of binder. Since the thickness of adhesive layer is relatively small, ink-jet printing is now widely used to easily obtain thin layer and design the pressure sensitive adhesive shape of different parts. So how to get superior performance pressure sensitive adhesive which is suitable for ink-jet printing become an urgent problem in printed electronics. The experiment was conducted through solution copolymerization of various vinyl monomers which were selected on the principle of solvent parameter prepared by free radical polymerization. The monomer, initiator mixture solution was dropped in continuous and synchronization process. By regulating the amount of initiator and polymerization temperature, we could effectively reduce the system viscosity and prepare high quality high-solids acrylate UV-curable pressure sensitive adhesives with low viscosity for ink-jet printing. The influence of initiator, solvents, transfer reagents and temperature on the structure and properties of the resin were discussed.
