Abstract

Under the alkaline condition of sodium hydroxide

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 (

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℃

reaction time was 1. 5h

(HTPB) :

(ECH) :

(NaOH) :

(TBAB) = 1:2. 9:3:0. 03.
