Tensile Performance

The samples were modified by using chlorinated polyethylene (CPE) to increase the toughness and using dioctyl phthalate (DOP) to increase the plasticity. The tensile strength and breaking elongation of the samples were studied by changing the chlorinated polyethylene (CPE) and dioctyl phthalate (DOP) contents and the hot-pressing temperature. It was shown by the test results that, with the increase of chlorinated polyethylene (CPE) and dioctyl phthalate (DOP) contents, the tensile strength of the samples was decreased while the breaking elongation was increased. By increasing the hot-pressing temperature, the blending effect between polyvinyl chloride (PVC) and chlorinated polyethylene (CPE) as well as the mechanical performance of the samples were increased, however, over-high hot-pressing temperature would result in plasticizer precipitation.

Average Size

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.
