Hi, I am taking a polymer science class, and my professor is no help, unfortunately so I came here to seek help....

The lab that we did was a Preparation of Nylon 6-10 by an Interfacial Polymerization Technique. Here is my description of the lab:

A solution of 3.ml (0.014 mol) of sebacoyl chloride was dissolved in 100 ml of anhydrous tetrachloroethylene. A solution of 4.4 g (0.038 mol) hexamethylenediamine was then dissolved in 50 ml water and carefully poured over the acid chloride solution above so as not to mix the two solutions together. At the interface of the two immiscible liquids, the polyamide film was pulled out continuously as the reactant continued to turn into product. The polymer product was washed with 50% aqueous ethanol, dried, and weighed.

We have to calculate the fractional conversion of the reaction into Nylon 6-10, and I don't know whether we are supposed to include the SOLVENT in the calculations.

Please help me! What do I do? Do I include the solvent in my calculations or not?

Thanks!!!

Does the solvent react? 
If you use twice as much solvent or half as much do you think the amount of nylon formed at the interphase will change?
