Evaluation of mechanical and thermal properties after chemical degradation of PVC and HDPE geomembranes
(2013-06-10)
Chemical compatibility between geomembranes and site-specific waste liquids should be assessed since the waste liquids are highly complex mixtures. This paper presents some considerations about the chemical compatibility ...
Biodegradation of a polylactic acid/polyvinyl chloride blend in soil
(Wiley-Blackwell, 2012-07-05)
This study investigated the microbial action in soil on poly(L-lactic acid) (PLLA) and polyvinyl chloride (PVC) films and a PLLA/PVC 7 : 3 blend, using Fourier transform infrared spectroscopy (FTIR), contact angle and ...
Biodegradation of blend films in soil and soil with chorume. I. PVC/PCL
(Research Journal Biotechnology, 2007-11-01)
Blends of synthetic and biodegradable polymers can be important in attaining material plastic degradation in the environment. Biodegradation using soil and chorume (liquid waste from landfill) microorganisms is a promising ...
Plasma Treatment to Improve the Surface Properties of Recycled Post-Consumer PVC

Thermo-gravimetric analysis (TGA) after different exposures of high density polyethylene (HDPE) and poly vinyl chloride (PVC) geomembranes
(2012-12-03)
This paper presents the results of thermogravimetric analysis (TGA) tests in PVC (1.0; 2.0 mm) and HDPE (0.8; 2.5 mm) geomembranes exposed to weathering and leachate after 30 months. The aim of this paper is the comparison ...
Ftalato de di-(2-etilexila) (DEHP) em bolsas de PVC para soluções parenterais de grandes volumes
(2005-12-01)
Large volume parenteral solutions (LVPS) are widely used as vehicles for intravenous administration of drugs and polyvinyl chloride (PVC) flexible bags are, nowadays, the plastic containers most commonly used to pack and ...
Morphological Changes in Poly(Caprolactone)/Poly(Vinyl Chloride) Blends Caused by Biodegradation
(Springer/plenum Publishers, 2010-03-01)
The biodegradation of blends of poly(caprolactone) (PCL) and poly(vinyl chloride) (PVC) has been studied. Blends of composition PCL/PVC 1:1 and 1:2 w/w were tested. The 1:1 blend contained crystals in the as-cast state and ...
Vida útil e metabolismo de carboidratos em raízes de mandioquinha-salsa sob refrigeração e filme de PVC
(Pesquisa Agropecuária Brasileira, 2019)
Photodegradation of polycaprolactone/poly(vinyl chloride) blend
(Elsevier B.V., 2008-01-01)
The photodegradation of a 1:1 w/w blend of polycaprolactone and poly(vinyl chloride) has been studied by following carbon dioxide emission during UV exposure. Similar measurements were performed for polycaprolactone and ...
Electrochemical modified electrodes based on metal-salen complexes
(Taylor & Francis Inc, 2007-01-01)
A general view of the electroanalytical applications of metal-salen complexes is discussed in this review. The family of Schiff bases derived from ethylenediamine and ortho-phenolic aldehydes (N,N'-ethylenebis(salicylideneiminato) ...
