Alternatives to PVC

Alternatives to PVC: An Economic Analysis

This much should be self-evident: a material should not be used in green buildings if it is uniquely toxic or carcinogenic, if it causes high levels of harm to workers, communities, and the natural environment both in production and in disposal. Rather, replacement of such a material with less toxic alternatives should be a priority for environmentally concerned architects, designers, and build...

Cell Adhesion to Plasma-Coated PVC

To produce environments suitable for cell culture, thin polymer films were deposited onto commercial PVC plates from radiofrequency acetylene-argon plasmas. The proportion of argon in the plasmas, P(Ar), was varied from 5.3 to 65.8%. The adhesion and growth of Vero cells on the coated surfaces were examined for different incubation times. Cytotoxicity tests were performed using spectroscopic me...

Experimental PVC Material Challenge in Subjects with Occupational PVC Exposure

BACKGROUND Polyvinyl chloride (PVC) materials have been linked to asthma in several epidemiologic studies, but the possible causal factors remain unknown. PARTICIPANTS We challenged 10 subjects experimentally to degraded PVC products under controlled conditions. All of the subjects had previously experienced respiratory symptoms suspected to be caused by this kind of exposure in their work pl...

Opening New Gates for the Modification of PVC or Other PVC Derivatives: Synthetic Strategies for the Covalent Binding of Molecules to PVC

Several synthetic strategies based on the use of substituted aromatic and hetero-aromatic thiols for the covalent binding of modifier compounds to PVC are described. A variety of aliphatic alcohols and amines are linked to the aromatic or heteroaromatic rings via highly active functionalities as the isocyanate, acidchloride, or chlorosulfonyl group, and the three chlorine atoms of trichlorotria...
