Study on the Frontal Polymerization of Polyurethane/Hollow Glass Microsphere Hybrid Material

In this article, we use propylene glycol (PPG), Chain expansion agent 1, 4-Butylene Glycol (BG), toluene diisocyanate (TDI) and hollow glass microsphere Sol as raw materials to prepare polyurethane/hollow glass microsphere hybrid materials by frontal polymerization. Here we studies how the front position varies with time and how the polymer viscosity influences the reaction rate in the frontal polymerization process, and through the comparisons with autoclave polymerization, draw to a conclusion that we can also get polyurethane/hollow glass microsphere hybrid materials by this new preparation and processing method.
