Photochemical reactions in poly(vinyl chloride)/poly(vinyl alcohol) blends

Journal of Photochemistry and Photobiology A: Chemistry, 2005
Abstract Poly(vinyl chloride) and poly(vinyl alcohol) (PVAL) blends with various molar ratios were UV-irradiated ( λ = 254 nm) at room temperature and in air atmosphere. Photochemical reactions were monitored by FTIR and UV–vis absorption spectroscopy.

The solubility of vinyl chloride in poly(vinyl chloride)

Die Angewandte Makromolekulare Chemie, 1975
AbstractThe solubility of vinyl chloride monomer (VCM) in PVC powders has been studied by equilibrium vapor pressure and microbalance gravimetric techniques at temperatures from 30 to 110°C. At temperatures and VCM concentrations above the glass transition, the solubility closely follows the Flory‐Huggins equation with χ = 0.98 and is independent of ...

Pyrolysis of poly(vinyl chloride)

Journal of Polymer Science: Polymer Chemistry Edition, 1974
AbstractA pyrolysis–gas chromatography–mass spectrometric technique has been developed to study the thermal degradation of poly(vinyl chlorides) polymerized at different temperatures. Hydrogen chloride and benzene evolution during successive stages of pyrolysis have been quantitatively determined and correlated to the tacticity and molecular weight of ...

Poly(vinyl chloride) and related polymers

1973
In this chapter the homopolymer, poly(vinyl chloride) (PVC) is considered together with vinyl chloride-vinyl acetate copolymers and other vinyl chloride copolymers of lesser importance. Also discussed are the commercially important copolymers of vinylidene chloride.

Plasticisers for Poly(Vinyl Chloride)

Progress in Rubber and Plastics Technology, 1995
Large quantities of organic esters are sold as plasticisers for poly(vinyl chloride) (PVC). They act by reducing the glass transition temperature of the polymer, resulting in the formation of a product which possesses flexibility and softness, as opposed to the inherently rigid starting material.
