Question about Polyester, Polymer and PET

[Ricardo Felli]

I hope someone knowledgeable could enlighten me about the following -
I'm doing a report on plastics and need help figuring out some of the
details. Thanks in advance!

What is the difference between polyester and polymer - is polyester a
type of polymer or is it made from polymer or something else?

Is PET a type of polyester? Or is polyester a different product made
from the same source? (I've noticed polyester is used - or referred to
- in products such as apparel, whereas PET ıs in particle form
and used in making bottles).

What are TPA and DMT? Are they exclusively used for making PET - or
are they used in producing other polyester products, as well? (Is DMT
or TPA used in making a polyester fleece, for example?)

Thanks!

PET is polyethylene terephthalate. Same polymer can be used to make bottles
and fibers.

DMT is dimethyl terephthalate and TPA is terephthalic acid. They are
monomers and either can be used with ethylene glycol to make PET.

You can use google to find out a lot about these topics. Your
questions are probably a bit simple for most people here to spend much
time answering. As I'm waiting for folks to get ready for lunch ....

What are TPA and DMT?

thermal polyaspartate and dimethyl terephthalate

Use google with search terms: polymer TPA
then with" polymer DMT

You'll find lots of stuff.

There's also an elderly DMT compound- Dimethyl Tryptamine- which, when
ingested, will make Everything clear... ^..^
