We actuated poly(vinyl chloride) (PVC) gel by applying a do field, and found localized creeping deformation, which induced swift, huge bending like a joint. The bending angle reached ca.150° at maximum at the field of 1000 V mm-1 with the velocity of ca. 90° s-1. The electric current was very small and in the range of 68 nA cm-2 . The mechanism of reversible, marked bending was studied using blocking and contact electrodes. The gel consisted of PVC and dioctyl phthalate (DOP), and was free of electrolytes. The concept is simple and applicable to conventional polymer materials. It could serve for developing new classes of soft and durable mechanically functional materials.

Abstract A novel environmental friendly plasticizer (TPE) derived from tung oil fatty acid with long fatty acid chain and high degree of branching was synthesized. Chemical structure of the obtained TPE was characterized with Fourier transform infrared spectroscopy (FT-IR) and 1H NMR. TPE was used to prepare plasticized PVC blends as main plasticizer. Thermal stability, mechanical properties and migration resistance of poly (vinyl chloride) plasticized with TPE were investigated. The results showed that torque data of plasticized PVC blends reached 12.4 N·m when the mass of the TPE was 50 wt.%. TPE improved the thermal stability of PVC blends obviously than dioctyl phthalate (DOP). The leaching tests showed that PVC plasticized with TPE were with higher migration resistance than that of DOP. The excellent thermal stability and high migration resistance of PVC blends showed high application value for TPE.

Compression Data

Abstract The mechanical behavior, morphological characterization and constitutive modeling of plasticized poly(vinyl chloride) (or PVC) are studied in this paper. The plasticized PVC is tested to large strains over a broad range of strain rates. Uniaxial and plane strain compression data at various constant strain rates ranging from −0.001 to −10 s−1 are collected on a conventional servohydraulic test system. Additional uniaxial impact compression data at approximately constant strain rates ranging from −1160 to −5560 s−1 are obtained using an aluminum split Hopkinson pressure bar apparatus. The large strain load/unload response of the plasticized PVC is nonlinear, it contains hysteresis and plastic deformation, and the initial response is highly rate dependent when the strain rate spans the transition zone between quasi-static and impact strain rates at room temperature. The morphology of plasticized PVC is analyzed via differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA), and described as a physically entangled network. A three-dimensional rate dependent constitutive model for plasticized PVC is developed and shown to successfully predict its stress—strain behavior over a broad range of strain rates.

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.

Two Parameter

Experimental Oxygen Index data taken on plasticized poly(vinyl chloride) systems which consisted of just poly(vinyl chloride) resin, PVC, and plasticizer are shown to obey a simple two-parameter equation for plasticizer loadings above 15 weight percent. The empirical equation is further tested using data for similar plasticized PVC compounds based on large number of commercial plasticizers and plasticizer blends. One parameter used in the equation is the Oxygen Index of the pure plasticizer determined using a simple modification of the standard Oxygen Index test procedure. The other parameter is shown to have essentially the same value for all the plasticizers tested. A detailed deriva tion of the empirical model is provided using published flame spread models adapted for the Oxygen Index test. Predictions of the Oxygen Index for the two-component (ideal) plasticized PVC compounds are within 2-3% of the ex perimentally measured values.
