When 3-methyl-1-butene is treated with a catalytic amount of BF 3 and H 2 O, a cationic
Question:
When 3-methyl-1-butene is treated with a catalytic amount of BF3 and H2O, a cationic polymerization process occurs, but the expected homopolymer is not formed. Instead, a random copolymer is obtained.
(a) Explain why there are two different repeating units.
(b) Draw a segment of the random copolymer that is formed, clearly showing the two different repeating units.
(c) Would you expect cationic polymerization of 3,3-dimethyl- 1-butene to produce a random copolymer as well? Justify your answer.
