Poly vinyl chloride information structure and properties.

Vinyl chloride repeat units.

Solution for an alternating copolymer which has a number average molecular weight of 250 000 g mol and a degree of polymerization of 3500 we are to determine one of the repeat unit types if the other is. Amorphous density at 25 o c. If one of the repeat units is ethylene which of styrene propylene tetrafluoroethylene and vinyl chloride is the other repeat unit. In this case the repeat unit has the same atoms as the monomer vinyl chloride ch 2 chcl.

When the polymer is formed the c c double bond in the monomer is replaced by a c c single bond in the polymer repeat. One of the simplest repeat units is that of the addition polymer polyvinyl chloride ch 2 chcl n whose repeat unit is ch 2 chcl. Molecular weight of repeat unit. The repeating units take on the linear homopolymer arrangement illustrated in.

Vinyl chloride is an organochloride with the formula h 2 c chcl that is also called vinyl chloride monomer vcm or chloroethene this colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride pvc. Most of the vinyl chloride produced in the united states is used to make a polymer called polyvinyl chloride pvc which consists of long repeating units of vinyl chloride. The chemical structure of the vinyl chloride repeating units is. Production of vinyl chloride in the united states grew at an average rate of about 7 from the early 1980s to the early 1990s with current growth at about 3 annually.

Pvc was first prepared by the german chemist august wilhelm von hofmann in 1872 but it was not patented until 1912 when another german chemist friedrich heinrich august klatte used sunlight to initiate the polymerization of vinyl chloride. Vinyl chloride ch 2 chcl is most often obtained by reacting ethylene with oxygen and hydrogen chloride over a copper catalyst. It is a carcinogenic gas that must be handled with special protective procedures. As a polymer repeating unit its chemical structure is.

If one of the repeat units is styrene which of ethylene propylene tetrafluoroethylene and vinyl chloride is the other repeat unit.
