A polyisocyanate curing agent, which is mainly composed of toluene diisocyanate (TDI) trimer, was prepared in the presence of the base metalcarboxylate K-1000.
A polyisocyanate curing agent, which is mainly composed of toluene diisocyanate (TDI) trimer, was prepared in the presence of the base metalcarboxylate K-1000. The reaction conditions were studied.
The novel methods for synthesis of ethoxylated fatty alcohol carboxylate (AEC) by catalytic oxidation with a stable free radical nitroxide or a noble metal catalyst were reviewed.
