A method of low-molecular-weight polystyrene being prepared by styrene using microreactor, by the way that monomer styrene and initiator toluene solution are inputted from two different arrival ends of T-shaped micro-mixer respectively, enter after mixing and carries out polymerization reaction in reacting pipe, after the purified drying of product, powdered polystyrene is obtained；The present invention makes to shorten within 30min the time required to sufficiently reacting, and reaction temperature is 60~140 DEG C, and product dispersion index is 1.1~2.0, and number-average molecular weight is adjustable in 1000~10000 ranges, has good promotion prospect. |
