Vinyl chloride 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. Compute repeat unit molecular weights g mol for poly vinyl chloride. Compute repeat unit molecular weights g mol for poly ethylene terephthalate. Crystalline density at 25 o c.

Molecular weight of repeat unit. Molecular weight of repeat unit. B compute the number average molecular weight for a polystyrene for which the degree of polymerization is 25 000. Amorphous density at 25 o c.

About 13 billion kilograms are produced annually. 14 4 a compute the repeat unit molecular weight of polystyrene. 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. Compute repeat unit molecular weights g mol for polydimethylsiloxane.

Molar volume v m. 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. 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. Compute repeat unit molecular weights g mol for polycarbonate.

Poly vinyl chloride information structure and properties. Calculate the repeat unit molecular weight of poly vinyl chloride in g mol. 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. It is polymerized in suspension or emulsion processes using free radical.

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. 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. The distinct piece of each monomer that is incorporated into the polymer is known as a repeat unit or monomer residue.

Use table 4 3 p110 textbook. In this case the repeat unit has the same atoms as the monomer vinyl chloride ch 2 chcl. Solution a the repeat unit molecular weight of polystyrene is called for in this portion of the problem.
