Phthalic Anhydride derived Polyesters and Nylon structures+reactions?

AI Thread Summary
Phthalic anhydride reacts with ethylene glycol to form a polyester through a condensation reaction, where hydroxyl groups from the glycol react with the anhydride, releasing water. Glycerin can also react similarly to produce a different polyester structure. Nylon is synthesized from sebacoyl chloride and hexamethylenediamine, involving a similar condensation mechanism that forms amide linkages. Understanding the specific structures of these polymers requires knowledge of their chemical reactions and the resulting polymer chain configurations. Further study of these reactions will clarify the polymer structures and their properties.

Phthalic Anhydride derived Polyesters and Nylon structures+reactions?

Homework Statement


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.

Homework Equations

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.

oops the pictures for the different chemicals don't work, ill try and fix it
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
