1- Discuss uses, other than molecular separation, for solids formed from the following types of molecules

2- The two main methods available to bring about molecular structural changes in polymers are (a) using a different monomer or (b) carrying our substitution reactions on a performed polymer. Discuss the advantages and disadvantages of each method. Give Examples.

Answer each of the following questions in less than two-typed, double-spaced pages (example font sizes: 11 point Arial or 12 point Times) 1Discuss uses, other than molecular separations, for solids formed from the following types of molecules. Perhydrotriphenylene Spirocyclophospha/enes Q O The two main methods available to bring about molecular structural changes in polymers are (a) using a different monomer or (b) carrying out substitution reactions on a preformed polymer. Discuss the advantages and disadvantages of each method. Give examples

Explanation / Answer

Solution:

1) The molecules polymerized using spiro techniques are used in biomedical and medicinal applications.

2) Subsitution reaction is favoured as addition of monomers forms unstable molecule, while (nucleophilic) spiro substitution makes an strong molecule by formation of radical.
