Yang Jian-zhou · China Pulp & Paper Industry · 2010
Synthesis of glycidyl triethyl ammonium chloride(GTA) by using triethylamine(TEA) and epichlorohydrin(EPIC) under ultrasonic condition were studied. The effects of ultrasonic frequency,molar ratio of material,reaction medium on yield of GTA were optimized. Synthesis of low degree substitution of cationic polyvinyl alcohol with GTA modified polyvinyl alcohol(PVA) ,the effects of temperature,molar ratio of material on DS and RE of cationic polyvinyl alcohol were studied. Analysis of the product structure by IR characterization was carried out. The results show that cationic polyvinyl alcohol DS=0.0346,RE=82.9%,has good cationic performance to meet the requirements for paper sizing.
