Naugard I-4 is a commercially proven polymerization inhibitor used to reduce polymer formation in monomer manufacture processes.
* Styrene distillation
* Divinylbenzene distillation
* p-methylstyrene distillation
* Superior performance to dinitrophenol polymerization inhibitors, especially at elevated temperatures
* Dramatic decrease in viscosity of tars
* High solubility in ethylbenzene and styrene monomer
* Low toxicity
* Attains maximum performance in the presence of air |
