Synthesis of quaternary ammonium cationic polymer PEA

摘要

The cationic polymer PEA was synthesized by ring-opening reaction and quaterisation with epichlorohydrin and β-hydroxy alkyl propyl ether amine as the main materials.Study on the efffect of rate of charge, reaction time and reaction temperature on cationic degree and epoxy value. Capability of adsorption on the sand and anti-swelling resistance were studied. The results showed that the best polymerization conditions as follows,reaction temperature was 60 °C, reaction time was 6 h, the rate of charge of epichlorohydrin to β-hydroxy alkyl propyletheramine was 2.5:1. Under these conditions , the cationic degree of PEA was 3.962 mmol/g, epoxy value was 0.12. Then it was performed the water absorption.
