The table below shows a number of structural units that are components of polymer repeat units; each is labeled with a letter enclosed in parentheses. For each of the following polymers, enter the letters of all of structural units that are found in its repeat unit as well as the number of each structural unit. For example, the polyethylene repeat unit is composed of 2(A) structural units. Write the formula without blanks or any intermediate symbols.

(A) (B) (C) (D) (E) (F) (G) (H) (I) (J) (K) (L)
