I am looking for a way for rapid polymerization in very mild conditions (without pressure, temprature...). Actually I have done it with N-isopropylacrylamid (monomer) , DMPA(initiator) and TMPTA (crosslinker) under iradiation UV light. I got the polymer which lasts two minutes to get solid. I need to do it faster. I am looking for another initiator also looking for a photoacid or photobase to catalyse the reaction. I should mention that the reaction I do is in aqueous solution so I have to use material insoluble in water. Does anyone has any suggestion?
