the polyhydroxylated polybutadiene (PHPB) was synthesized by hydroxyl terminated polybutadiene ( HTPB) and epichlorohydrin (ECH). Tetrabutyl ammonium bromide (TBAB) as the catalyst in this reaction. The structure and thermal stability of raw material
intermediate products and product were analyzed by Infrared spectroscopy (IR)
thermogravimetry (TG) and nuclear magnetic resonance (
1
H- MNR). The effect of reaction temperature
reaction time
raw material ratio
catalyst dosage and dosage of sodium hydroxide on the on the PHPB synthesis were investigated in detail by the hydroxyl value
viscosity and yield of the product. The result showed that the optimum synthesis conditions were as follows : reaction temperature was 55℃
