Why does vinyl acetate not polymerize
Thread Content
In the vinyl acetate polymerization experiment, vacuum distillation was carried out at 40°C and a vacuum pressure of 0.09 MPa to obtain vinyl acetate. After being left undisturbed for 100 hours, no changes occurred. Heating at 70°C for an hour caused no changes. I would like to ask the teachers why? Isn’t it said that vinyl acetate monomer polymerizes easily? If I want to polymerize monomers, what experimental conditions are required?
Interesting, your data? It puzzles me as well; I’d like to hear experts’ opinions
The boiling point of vinyl acetate is 72°C; therefore, the reaction temperature must be above this value, and a catalyst is required. Vinyl acetate monomer can polymerize on its own, but it requires high temperatures and a long time.
