Vinyl chloride repeat unit.

Compute repeat unit molecular weights g mol for polydimethylsiloxane. Solution a the repeat unit molecular weight of polystyrene is called for in this portion of the problem. B compute the number average molecular weight for a polystyrene for which the degree of polymerization is 25 000. Atomic weights for several elements are included in the following table.

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

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 poly ethylene terephthalate. 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. About 13 billion kilograms are produced annually.

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. Compute repeat unit molecular weights g mol for poly vinyl chloride. 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. Molar volume v m.

In this case the repeat unit has the same atoms as the monomer vinyl chloride ch 2 chcl. It is polymerized in suspension or emulsion processes using free radical. Molecular weight of 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.
