Hydrothermal carbonization of poly(vinyl chloride)
Chemosphere, 2015Poly(vinyl chloride) (PVC) was subjected to hydrothermal carbonization in subcritical water at 180-260 °C. Dehydrochlorination increased with increasing reaction temperature. The release of chlorine was almost quantitative above ∼235 °C. The fraction of organic carbon (OC) recovered in the hydrochar decreased with increasing operating temperature from ...

Abstract From the literature, it is well known that poly(caprolactone)/poly(vinyl chloride) (PCL/PVC) and poly(caprolactone)/chlorinated poly(vinyl chloride) (PCL/CPVC) blends are miscible, at any composition. However, PVC and CPVC are immiscible. It is shown, in this study, that the addition of PCL to a PVC/CPVC mixture allows the observation of a ...

AbstractBlends of poly(vinyl chloride) with chlorinated poly(vinyl chloride) (PVC), and blends of different chlorinated poly(vinyl chlorides) (CPVC) provide an opportunity to examine systematically the effect that small changes in chemical structure have on polymer‐polymer miscibility.

Thermal gelation of poly(vinyl chloride)
Polymer International, 1995AbstractThe dynamic and isothermal gelation points of poly(vinyl chloride) (PVC) were determined using spectrophotometric and viscometric techniques. Four different PVC samples, with viscosity‐average molar masses of 70 000, 90 000, 106 000 and 141 000, were used. The dynamic thermal gelation points of PVC samples heated to temperatures between 120 and

Photostability of Poly(Vinyl Chloride)/Poly(Vinyl Alcohol) Blends
Molecular Crystals and Liquid Crystals, 2004Photooxidative degradation and photocrosslinking of poly(vinyl chloride), poly(vinyl alcohol)and their blends with different components ratio has been investigated in accelerated laboratory conditions. It was found that PVC is less photostable than PVAL, in which the photocrosslinking is more efficient.

Modification of poly(vinyl chloride). XXXIV. Crosslinked poly(vinyl chloride) via paste‐processing
Die Angewandte Makromolekulare Chemie, 1978AbstractA novel PVC‐crosslinking technique using 6‐dibutylamino‐1,3,5‐triazine‐2,4‐dithiol (DB) was applied for a paste processing to produce a crosslinked PVC product. The paste formulation recommended in the present study consisted of 100 parts of PVC (Zeon 121), 60 parts of dioctyl phthalate, 0.2 parts of MgO, and 6 parts of a 50% solution of DB‐Na ...

Poly(vinyl chloride) Nanocomposites
Journal of Macromolecular Science, Part A, 2014Poly(vinyl chloride) is one of the major thermoplastics beside other commodities polymers like polyethylene and polystyrene. However, some of its main characteristics such as plasticity, thermal and photo stability are inferior to other commodity polymers.

High-rate thermomechanical behavior of poly(vinyl chloride) and plasticized poly(vinyl chloride)
Journal de Physique IV (Proceedings), 2006A combined experimental and analytical investigation was carried out in order to develop predictive capabilities for the rate-dependent behavior of poly(vinyl chloride) (PVC) and a dioctyl phthalate (DOP)-plasticized PVC, with focus on predicting the thermo-mechanically coupled behavior under high rates of deformation.

Abstract The thermal decomposition of chlorinated poly(vinyl chloride) and three plasticized chlorinated poly(vinyl chloride) systems has been investigated. The routes of decomposition of these systems have been elucidated by investigating char formation and by using a combination of thermogravimetric analysis (TGA) and prolysis/gas ...

Determination of residual vinyl chloride in poly(vinyl chloride) resins
Journal of Chromatography A, 1980Abstract The determination of residual vinyl chloride (VC) in poly(vinyl chloride) (PVC) powders based on thermal desorbtion in a carrier gas stream and trapping of the VC is described. A trap is installed in the heated injection port of a gas chromatograph and desorbed volatiles are chromatographed by a two-stage chromatographic system.
