2.6 You have supplies of the five reagents below. Consider only the free radical and condensation reactions discussed in chapter 2 and assume that they can be carried out completely and irreversibly. (A) Describe (show the reagents and reaction steps) how you would make a graft copolymer with the branches distributed randomly along the main chain, and with no possibility of crosslinking. Show the main-chain and branch repeating units. (B) Describe how you would make a block copolymer ( AxByAz, with x,y and z not necessarily being the same). Show the A and B repeating units
