Chapter 30: Question 30.16 (page 1213)

Draw the structure of PEF, polyethylene furanoate, a condensation polymer formed from furandicarboxylic acid and ethylene glycol. PEF, which can be synthesized from precursors that are obtained from renewable resources, has many of the same properties as polyethylene terephthalate (PET).

Short Answer

Answer

Polyethylene furanoate

Step by step solution

01

About PEF

PolutheneFuranoate (PEF), is a polymeric substance produced by polycondensation reaction. The starting materials required to get this polymer are furan dicarboxylic acid and ethylene glycol.

02

About the reactants

Both the reactants contain a hydroxyl group at the end of the chain. This makes the active site for the polymerization reaction. The condensation reaction means, there will be condensing or removal of some substances to form another molecule.

03

About the reaction

The hydroxyl groups present at the end of both the ends of monomers get condensed and oxygen atom attaches there. The reaction is shown below.

Researchers at Rutgers University have developed biocompatible polymers that degrade into nonsteroidal anti-inflammatory drugs. For example, the reaction of two equivalents of benzyl salicylate and one equivalent of sebacoyl chloride forms a poly(anhydride ester) called PolyAspirin, which hydrolyzes to salicylic acid (an anti-inflammatory agent) and sebacic acid, which is excreted. This technology can perhaps be used for localized drug delivery at specific sites of injury. What is the structure of PolyAspirin?

Compound A is a novel poly(ester amide) copolymer that can be used as a bioabsorbable coating for the controlled release of drugs. A is a copolymer of four monomers, two of which are amino acids or amino acid derivatives. The body鈥檚 enzymes recognize the naturally occurring amino acids in the polymer backbone, allowing for the controlled enzymatic breakdown of the polymer and steady release of an encapsulated drug. Identify the four monomers used to synthesize A; then use Figure 29.2 to name the two amino acids.

Poly(ester amide) A

Cationic polymerization of 3-phenylpropene (CH2=CHCH2PH)affords A as the major product rather than B. Draw a stepwise mechanism to account for this observation.

Draw a stepwise mechanism for the following reaction, which is used to prepare bisphenol A (BPA), a widely used monomer in polymer synthesis.

The reaction of urea [(NH2)2 C=O] and formaldehyde (CH2=O) forms a highly cross-linked polymer used in foams. Suggest a structure for this polymer. [Hint: Examine the structures of Bakelite (Figure 30.7) and Melmac (Problem 30.58).]
