2. A solid sample of one of the following polymers (PETE, PP, PVDC and PTFE) was found to be insoluble in toluene, acetic acid, formic acid, as well as DMF and DMSO (not shown in Scheme 1). The polymer sinks in an ethanol- water (4:1) solution but floats in an ethanol-water (10:7) solution. Identify the polymer.

A3 Anionic polymerization of styrene is generally known to produce polymers with a narrow molecular weight distribution. Explain the reason for this.
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’s enzymes recognize the naturally occurring amino acids in the polymer backbone, allowing for 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.Figure 29.2: The 20 naturally occurring amino acids
Poly(3-hydroxybutanoic acid), a biodegradable polyester, is an insoluble, opaque ma- terial that is difficult to process into shapes. In contrast, the copolymer of 3-hydroxy- butanoic acid and 3-hydroxyoctanoic acid is a transparent polymer that shows good solubility in a number of organic solvents. Explain the difference in properties between these two polymers in terms of their structure. Poly(3-hydroxybutanoic acid) Poly(3-hydroxybutanoic acid- 3-hydroxyoctanoic acid) copolymer

How would you describe the homogeneity of a polylactic acid polymer chain based on melting point? The theoretical melting point was 150-160 degrees celsius for polylactic acid and the in lab observation yielded 153-154 degrees celsius for the melting point? Is homogeneity confirming purity? Is homogeneity confirming uniform lengths of the polymer chain? Is homogeneity confirming pure monomer units within the polylactic acid polymer chains? I am uncertain as to how to be specific that my melting point range indeed confirms homogeneity?
