CONCLUSIONS The isothermal Michael addition polymerizations of N, N'-bismaleimide-4, 4'-diphenylmethane (BMI) and barbituric acid (BTA) with BMI/BTA = 2/1 (mol/mol) in 1-methyl-2-pyrrolidone were investigated independently in this work.
It took some 40 years of such chemical dabbling before research on barbituric acid derivatives paid off.
The apparent concentrations of TNM in the samples were also determined by assaying 200-[micro]L aliquots with barbituric acid as the condensing reagent and quantifying results by comparison with a 56.
