Microporous Poly (vinyl chloride) (PVC) was prepared by foaming of PVC powders using the solution of 2, 2’-azo-bis-iso-butyronitrile (AIBN) in co-solvent of butanone and cyclohexanone when heated. The effect of composition of solvent and quantity fraction of AIBN also preferred dioctyl phthalate (DOP) on the structure of microporous PVC is discussed. The results indicated that much microporosity with average size of 0.2-2μm can be generated when acetone is selected as solvent, 2% DOP and 10% AIBN are used. The microporous PVC is a potential desirable reactor to prepare CaCO3 nanoparticle.
