Q: What are the functions of succinic anhydride (SA) and phthalic anhydride (PA) in the copolymerization process?
A: SA and PA serve as anhydride comonomers that react with EO to form ester linkages in the resulting copolymer. These ester linkages can be degraded under basic conditions, allowing for the synthesis of degradable polyethers.
