Vinyl Chloride Repeat Unit

There may be more than one structural unit in the repeat unit.

Vinyl chloride repeat unit.

Molecular weight of repeat unit. Compute repeat unit molecular weights g mol for poly ethylene terephthalate. Solution a the repeat unit molecular weight of polystyrene is called for in this portion of the problem. 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.

If one of the repeat units is styrene which of ethylene propylene tetrafluoroethylene and vinyl chloride is the other repeat unit. 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. The distinct piece of each monomer that is incorporated into the polymer is known as a repeat unit or monomer residue. Van der waals volume v vw.

Poly vinyl chloride information structure and properties. Compute repeat unit molecular weights g mol for poly vinyl chloride. 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. Calculate the repeat unit molecular weight of poly vinyl chloride in g mol.

Atomic weights for several elements are included in the following table. 14 4 a compute the repeat unit molecular weight of polystyrene. Compute repeat unit molecular weights g mol for polycarbonate. Crystalline density at 25 o c.

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. About 13 billion kilograms are produced annually. Compute repeat unit molecular weights g mol for polydimethylsiloxane. In this case the repeat unit has the same atoms as the monomer vinyl chloride ch 2 chcl.

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. Use table 4 3 p110 textbook. Molar volume v m. Click here to access table 14 3.

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. It is polymerized in suspension or emulsion processes using free radical. Amorphous density at 25 o c.
