Application of ultrasound and microwave technique in the synthesis of porous polymer matrixes

Porous polymer matrix having high specific surface area and abundant pore morphology were firstly prepared by ultrasound and microwave assisted synthesis.The investigation demonstrated that by the ultrasound or ultrasound-microwave assistant technique:1) porous resin(specific surface area:1320m2/g) could be obtained via the mutual-polymerization of 4,4'-dichloromethyl biphenyl(CMDP) and P-xylylene dichloride(XDC) monomers;2) hypercrosslinked porous adsorption fiber(specific surface area:84.25m2/g and 83.96m2/g) could be obtained via Fridel-Crafts post-crosslinking reaction on the PP-ST-DVB fiber.By contrast with the traditional synthetic method of porous polymer,the ultrasound and microwave assistant synthesis could effectively overcome the various disadvantages derived from the non-uniform heat transference during the solid phase polymerization,and possessed the advantages of accelerating swelling and reaction.
