Vinyl Chloride Repeat Unit

Solution a the repeat unit molecular weight of polystyrene is called for in this portion of the problem.

Vinyl chloride repeat unit.

Click here to access table 14 3. Use table 4 3 p110 textbook. 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. 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.

Compute repeat unit molecular weights g mol for poly ethylene terephthalate. Crystalline density at 25 o c. 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. Poly vinyl chloride information structure and properties.

The distinct piece of each monomer that is incorporated into the polymer is known as a repeat unit or monomer residue. Molecular weight of repeat unit. Calculate the repeat unit molecular weight of poly vinyl chloride in g mol. 14 4 a compute the repeat unit molecular weight of polystyrene.

Amorphous density at 25 o c. 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. Carbon chlorine 35 45 g mo fluorine 19 00 g mol hydrogen 1 008 g mo oxygen 16 00 g mol 12 01 g mol m 62 494 g mol if the degree of polymerization of this polymer is 26000. Some authors however define dp as the number of repeat units where for copolymers the repeat unit may not be identical to the monomeric unit.

If one of the repeat units is styrene which of ethylene propylene tetrafluoroethylene and vinyl chloride is the other repeat unit. Van der waals volume v vw. About 13 billion kilograms are produced annually. Molar volume v m.

Compute repeat unit molecular weights g mol for polycarbonate. Vinylidene chloride chemical formula ch 2 ccl 2 polymer repeating unit structure ch 2 ccl 2 can be made directly from ethylene and chlorine or by the further chlorination of vinyl chloride with subsequent removal of hydrogen chloride by alkali treatment. B compute the number average molecular weight for a polystyrene for which the degree of polymerization is 25 000. In this case the repeat unit has the same atoms as the monomer vinyl chloride ch 2 chcl.

Compute repeat unit molecular weights g mol for polydimethylsiloxane. It is polymerized in suspension or emulsion processes using free radical. Atomic weights for several elements are included in the following table.
