Polymerisation Equations (1 Viewer)

[Vizsla]

How would you write the equations for addition and condensation polymerisation???
Specifically cellulose for condensation and polyethylene for addition.

 

[Kaido]

n(CH2=CH2) -> ...-C-C-C-C-C-C-... (with the hydrogen sticking out obv) or ...-CH2-CH2-CH2-CH2-CH2-CH2-...
Cellulose is almost nvr asked (except in MC, in which they will give you a diagram)
But here: n(HO–C6H10O4–OH) → H–(O–C6H10O4)n–OH + (n – 1)H2O

Should there be an intermediate step for addition polymerisation with the free-radical?
