Chain fraction is styrene and unknown repeat units in an alternating copolymer, followed by each type of repeat unit. If the other is Styrene, a repeat unit of an alternating copolymer forms.

With the chemical formula C6H5CH=CH2, styrene is an organic substance. Although older samples may appear yellowish, this benzene derivative is an oily, white liquid. Although large concentrations have a less savoury flavour , the chemical readily evaporates and has a sweet smell of styrene. A copolymer is a polymer produced from more than one type of monomer in polymer science. Copolymerization is the process by which monomers are polymerized into copolymers. Bipolymers are the name given to copolymers created through the copolymerization of two monomer types. The formula for m is as follows: m = Mn / Dp m = 250000 / 3420 = 73.09g/mol.
