"Co-polymers" consist of two different monomers ("A" and "B") joined in analternating fashion (ABABAB...). Block co-polymers also consist of twodifferent monomers, but in this case, blocks of polymer containing only Aunits are joined to blocks of polymer containing only B units(AAAAABBBBB...). How block co-polymers are synthesized?
Proteins are naturally occurring polymers formed by condensationreactions of amino acids, which have the generalstructure In this structure, — R represents — H, — CH3, or anothergroup of atoms; there are 20 different natural amino acids,and each has one of 20 different R groups. (a) Draw the generalstructure of a protein formed by condensation polymerizationof the generic amino acid shown here. (b) When only afew amino acids react to make a chain, the product is called a“peptide” rather than a protein; only when there are 50 aminoacids or more in the chain would the molecule be called a protein.For three amino acids (distinguished by having three differentR groups, R1, R2, and R3), draw the peptide that resultsfrom their condensation reactions. (c) The order in which theR groups exist in a peptide or protein has a huge influence onits biological activity. To distinguish different peptides andproteins, chemists call the first amino acid the one at the “Nterminus” and the last one the…

An alternating copolymer is known to have a number-average molecular weight of 100,000 g/mol and a degree of polymerization of 2210. If one of the repeat units is ethylene, which of styrene, propylene, tetrafluoroethylene, and vinyl chloride is the other repeat unit? Why?
When polyethylene is made by free radical polymerization, the resulting polymer has a significant amount of branching, resulting in low-density polyethylene (see Section 26.9a). When styrene undergoes free radical polymerization, on the other hand, very little branching occurs. Explain this phenomenon.
