Dear Mahmut Ali Ermeydan, the attached file is a good review on polyamides. My Regards

Attached are another interesting documents.

Use adipoyl chloride instead of adipic acid.

Thanks for valuable answer, lets specify the situation. Well adipoyl chloride react better than adipic acid obviously. But I need a bulk polymerization, because interface polymerization seperates my material. I want to impregnate polymer into a material. So, can pI polymerize adipoyl chloride and hexamethylenediamin in DMF or whatever?

Hi Mahmut,

first you get the ammoniumsalt of the amine and the acid. To get the PA, you have to evaporate the water. But you will destill amine as well and so you will get no satisfying product.

Better you use, as still mentioned the acidechloride, or an ester of the acid.

There are lot of lab instructions about this.

But it is not simple to get a product, that can compet with commercial samples, why you dont use thous?

Obviously, low temperature polymerization fits to my aim. However, I dont want to make an interface polymerization bu a solution or bulk polymerization will be better.

Commercially they make the salt and heat under vacuum to 300 or 350 C.

How about ring opening the lactam?
