In the previous paper, we have reported that alcohol base multi-branched high molecular non-ionic surface active agents will give a good effect on the stability of COM.
This paper will compare the effect of the amine base multi-branched high molecular nonionic surface active agents with that of amine base low molecular nonionic surface active agents.
The results will show that the multi-branched high molecular nonionic surface active agents, the copolymer obtained by adding propylene oxide and ethylene oxide to polyethylenepolyamine, will maintain COM stable for more than 1 month of still storage at 70°C.
It will also be shown that conventional amine base low molecular nonionic surface active agents will give a very little COM stabilizing effect.
