Polyvinylchloride route

Hydrocarboxylation of the Ce-Cs a-olefins with cobaltcarbonyl/pyridine catalysts at 200 °C and 20 MPa gives predominantly the linear carboxylic acids. The acids and their esters are used as additives for lubricants. The Ce-Cio a-olefins are hydroformylated to odd-numbered linear primary alcohols, which are converted to polyvinylchloride (PVC) plasticizers with phthalic anhydride. Oligomerization of (preferably) 1 -decene, applying BF3 catalysts, gives oligomers used as synthetic lubricants known as poly-a-olefins (PAO) or synthetic hydrocarbons (SHC) [11, 12]. The C10-C12 a-olefins can be epoxidized by peracids this opens up a route to bifunctional derivatives or ethoxylates as nonionic surfactants [13]. 

EXPOSURE ROUTES Ingestion (food, drinking water) use of hemodialysis tubing polyvinylchloride bags containing intravenous solutions occupational exposure not absorbed through skin. 

An early example of the precursor route to PA was through polyvinylchloride (PVC). A base was used to remove an equivalent of HCl from every repeating unit of the PVC backbone, leaving a conjugated structure (Scheme V) [57-59]. In a ical experiment.
