“…In previous studies, the use of various nitrogen compounds has been reported, among others are oligomers of 4-vinylpry dine (Ilim et al, 2021b;Ilim et al, 2016e), oligomer of 2vinylpyridine (Ilim et al, 2021d) , oligomer of 4-vinylpiperidine (Ilim et al, 2017c) , and ethylenediamine and tetraethylenepentamine (Mahmmod et al, 2019) . In the context of nitrogen compounds preparation, other potential raw materials are vegetable oils, considering their availability, renewability, biodegradability, and non-toxicity.…”
