Sulfurization polyvinyl chloride
Russian Journal of Applied Chemistry, 2013A sulfurized polymer comprising 57.64% of chemically bound sulfur characterizing by paramagnetism with the concentration of paramagnetic centers 2 × 1019 spins g−1 and g-factor 2.0043 was resulted n the treatment of industrial polyvinyl chloride by elemental sulfur.

In 1987, some 1,320 kt PVC were manufactured in the Federal Republic [I]. Allowing for an export trade surplus of PVC moulding compounds (260 kt), PVC semi- finished goods (160 kt) and PVC in finished products or as packaging material (100 kt), approximately 800 kt pure PVC remained in the Federal Republic. All the figures are calculated with reference

PVC (polyvinyl chloride) [PDF]
, 2001 PVC was first produced on a large scale in the 1930s in Germany and production in the USA and the UK began soon thereafter (Matthews 1996). Worldwide production grew from about 6 million tonnes in 1970 to 17.5 million tonnes in 1989 (Johnson 1990) and 27.7 million tonnes in 1997 (Chemical Week 1998).

JAMA: The Journal of the American Medical Association, 1976
To the Editor.— The article "Polyvinyl Chloride Toxicity in Fires" by Dyer and Esch (235:393-397, 1976) contains a number of factual errors and certain misleading inferences. In three places, the combustion of polyvinyl chloride (PVC) is said to produce chlorine and phosgene.

Use of polyvinyl alcohol in the manufacture of polyvinyl chloride
British Polymer Journal, 1973AbstractThe stabiliser used in the suspension polymerisation of vinylchloride influences greatly the quality of the resulting polyvinyl chloride, in particle size and distribution, and the absorption rate of plasticiser, etc.The relationship between the manufacturing conditions of polyvinylalcohol (PV‐OH) and its dispersing power was studied using ...

Manufacture of polyvinyl chloride
1992The chlorine content of pure polyvinyl chloride is 56.77 %. In 1987 manufacture of PVC amounted to 1,320 kt [1), which corresponds to 749 kt chlorine. The primary chlorine carrier is elemental chlorine which is reacted with ethylene to form dichloroethane. On cracking dichloroethane to give vinyl chloride, hydrogen chloride is formed.

Processing of polyvinyl chloride
1992PVC is converted by all techniques applied for thermoplastic materials. By far the most important process is extrusion, followed by calendering. Paste processing occupies the third place among the processing methods. In paste processing sufficient plasticizer is added to the resin to enable it to be processed as a paste. This processing mode is limited

PHENOXYETHANOL ABSORPTION BY POLYVINYL CHLORIDE
Journal of Clinical Pharmacy and Therapeutics, 1984Phenoxyethanol was found to be absorbed by polyvinyl chloride administration sets during continuous irrigation therapy. Depending upon the conditions of administration up to 20% loss of potency could occur. Absorption of the drug by the rigid plastic luer-lock fitting of the set caused softening and decreased rigidity of the plastic.

Thermal aging of polyvinyl chloride
CEIDP '05. 2005 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2005., 2005This paper reports on the study of the thermal aging of the polyvinyl chloride used in high voltage cables. This study shows that thermal aging changes the electrical properties of the material. We notice that the higher the aging temperature is, the more important is the rate of degradation of the insulator.
