Unsaturated polyester resin

Postby Mehroz » Sat Mar 26, 2016 9:51 pm

Hey!! I want urgent help.
I am working on a study project to make unsaturated polyester resin from PET waste. I am stuck on the second step of the reaction. This involves the reaction between maleic anhydride and BHET. the product include polyester resin, BHET (inconverted) and maleic anhydride (unconverted).
My basic question is that how we can separate polyester resin from the unconverted BHET and maleric anhydride.
Any help would be appreciated.
Thx :)

I don't think there are any chemists here, just resin users! Sorry we can't help you with that question :(
Oh yeah I can make that....
