Polyester stereocomplexes, compositions comprising same, and methods of making and using same

A composition comprising:

• polymer chains that form one or more stereocomplexes,
• wherein the polymer chains comprise i) first enantiomeric polymer chains having a first enantiomeric structure that comprise individual repeat units having the following structure:
• and
• second enantiomeric polymer chains having a second enantiomeric structure that is the opposite absolute stereochemistry of the first enantiomeric structure that comprise individual repeat units having the following structure:
• or
• ii) individual repeat units having both Repeat Unit Structure I and Repeat Unit Structure II, and wherein R1 is selected from —(CH2)x—, wherein x is 2-6, cis or trans —CR3═CR4—, wherein R3 and R4 are selected from —H, —CH3, and —Cl, —CH2C(═CH2)—, ortho —C6H4—, —CH2OCH2—, 1,8-naphthylenediyl, and 3,4-cyclohexene-diyl,
• R2 is selected from —CH3, —CF3, C2 to C8 alkyl group or aryl group, —CH2OR5, wherein R5 is a C2 to C8 alkyl group or aryl group, and —CH2X, wherein X is Cl, Br, I, or F.
