Copolymerization Reaction

Poly(bis(2-(trimethylamino)ethyl) 2-hydroxyl propylidene ammonium) chloride (PTMAEPAC) is one kind of oligomeric cationic polymer with a quarter nitrogen atom on its main and side chain. It was synthesized from Bis(2-trimethyl ammonium)ethyl ammonium chloride (TMAEAC) and epichlorohydrin (ECH) by copolymerization reaction, effects of reaction temperature, mole ratio of raw materials, reaction time, amount of solvent on the cationicity of product were studied. The structure of PTMAEPAC was confirmed by IR and 1H-NMR, and its anti-clay-expanding ability was studied. The results show that the cationicity of PTMAEPAC can reach 83.9% with the reaction time of 6h at 65°C when TMAEAC-to-ECH mole ratio is 1.2:1 and the amount of solvent is 30% in total. According to the IR and NMR analysis the product has the same structure with the aim compound. When the content of the product is 3 wt% it has a good anti-clay-expanding ratio of 96.1%.
