    (See attachment for full description)

    Match the structures in the attachment to:

    48. produced by reactions in which each bond in the polymer is formed independently of the others.
    49. Isotaftic propylene
    50. Polymers obtained when two or more different monomers are allowed to polymerize together.
    51. a polyurethane
    52. Small organic molecules that act as lubricants between polymer chains.
    53. Amorphous polymers that have the ability to stretch out and spring back to their original shape
    54. Bakelite is this type of polymer
    55. a Ziegler-Natta catalyst

    56. Rank the monomers in the attachment in order of increasing reactivity toward cationic polymerization

    57. Monomer A is copolymerized with Monomer B and is found to have the following structure:

    The type of copolymer formed is:
    a. a random copolymer
    b. an alternating copolymer
    c. a block copolymer
    d. a graft copolymer

    58. Draw the structure(s) of the monomer(s) used to make the following polymer (attached).
    59. Classify the polymer in the attachment as step-growth or chain-growth
    60. Draw the structure of the polymer obtained from the reaction in the attachment.
