9. Consider the two polymers Nylon 6,10, with the degree of polymerization of 100 and poly(ethyl methacrylate) with the degree of polymerization of 1200. (a) Write chemical structures of the polymers. (b) What polymer will have a higher value of real end-to-end distance in bulk? Assume that the values of characteristic ratio and bond length are the same for these polymers. 1/2 The equation for the end-to-end distance: (²) 11² = α (nCN) 1/21

During our lectures on polymeric materials, I used polyethylene as an example because of its very straightforward structure. (a.) Hydrogen peroxide (H2O2) is used as an initiator for the polymerization of ethylene. Draw a diagram of a dissociated hydrogen peroxide molecule which emphasizes the creation of two free radicals (unbonded electrons) that can serve as initiators or as terminators of polymerization.

Proteins are naturally occurring polymers formed by condensationreactions of amino acids, which have the generalstructureIn 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 one at…

a) Calculate the % atom economy for the addition polymerization of polyethylene, where 280.5 g of ethylene monomers react to produce 280.5 g of polyethylene.   b) Calculate the % atom economy for the condensation polymerization of nylon-6,6, where 116.21 g of hexamethylendiamine monomers and 183.03 g of adipoyl chloride monomers react together to produce 226.32 g of nylon-6,6 product and 72.92 g of hydrogen chloride waste.

High density polyethylene (HDPE) and low density (LDPE) both are made from the same monomer (-CH2-)a one is transparent in appearance and one is whitish in colour. Identify which polymer has the transparent characteristic and which has the whitish colour and explain why such behavior is observed.

What is the fraction of monomers (p) that have been used in a stepwise polymerisation reaction if the reaction solution started with a monomer concentration of 1.58 mol L-1 and now has a concentration of 0.231 mol L-1?
