This study was performed to compare the amount of air leakage into the thoracic cavity associated with three thoracostomy tube materials (silicone, polyvinyl chloride, red rubber) in canine cadavers. Differences in intrapleural pressures (IPPs) measured before and after tube placement and before and after tube removal were calculated. The duration of air leakage around the tubes was assessed by...

Vinyl acetate is a colorless, flammable liquid that also has a characteristic smell that can quickly become irritating. This monomer is used principally in the production of polyvinyl acetate (PVAc) and other vinyl acetate co-polymers. Polyvinyl acetate is a precursor of polyvinilyc alcohol and polyvinyl acetate resins (PVA). Vinyl acetate is also copolymerized as a minor raw material for vinyl...

A patient who worked with polyvinyl chloride developed a malignant haemangioendothelioma of a toe. This rare tumour is more commonly found in the liver where it has been reported to arise in association with exposure to the vinyl chloride monomer.

in this research, the tacticity and microstructure of polyvinyl chloride (pvc) were studied through back bone methylene and methine carbons and protons splitting by carbon (13c nmr), proton (1h nmr) and two-dimensional (2dnmr) nulear magnetic resonance spectroscopy in deuterated etrahydrofuran.polyvinyl chloride was synthesized by emulsion polymerization of vinyl chloride (vcm) under pressure t...

Bacterial colonization of polymeric medical aids causing so-called nosocomial infections is one of the main problems linked with the extensive use of polymeric devices in clinical applications. In this study, the properties of medical-grade polyvinyl chloride were modified by incorporating crystal violet into its bulk structure. Sodium montmorillonite was used as a carrier for the crystal viole...
