Conclusions
-
1.
It was shown that it is theoretically possible to copolymerize ɛ-caprolactone with ɛ-caprolactam in the presence of triisobutylaluminum, which leads to the formation of poly(ester amides) with a high molecular weight.
-
2.
In order to find the optimum conditions for running the copolymerization process, a study was made of the effect of temperature, reaction time and amount of catalyst on the yield and viscosity of the formed copolymers.
-
3.
It was established that poly(ester amides) can be obtained by running the copolymerization of ɛ-caprolactam with ɛ-polycaprolactone in the presence of triisobutylaluminum.
