Phthalic Anhydride derived Polyesters and Nylon structures+reactions???? 1. The problem statement, all variables and given/known data Im doing a lab for Materials science for engineers. they want to know how phthalic anhydride and ethylene glycol makes a polyester. They also want to know how that and glycerin make a polyester. After that we made nylon from sebacoyl chloride and hexamethylenediamine. Im a first year student and I have no clue how these reactions work, they didnt teach us about the chemistry just the mechanical properties once the polymer chains are formed. 2. Relevant equations Phtalic anhydride: ethylene glycol: glycerin: sebacoyl chloride: hexamethylenediamine: 3. The attempt at a solution I figured that the OHs would probably react with each other on the ends of the molecule but I have no idea what the polyester structure would be of the either the phthalic anhydride derived polyesters or the nylon-6,10. I do know that there are probably two reactions from the ethylene glycol with the oxygens in the phthalic anhydride but nothing further than that.
