Abstract

Abstract: Polyhexamethylene guanidine hydrochloride was synthesized through high-temperature thermal condensation with guanidine hydrochloride and 1,6-hexanediamine as the main starting materials and polyethylene glycol-400 as solvent.The impact of the reaction conditions such as reaction temperature and time as well as molar ratio of the reactants and dosage of the solvent on the number average molecular weight M_n and the weight average molecular weight M_w of the product was studied,and the optimal polymerization process conditions were obtained.The product synthesized under the optimal process shows good molecular linear distribution and good antibacterial performance.

Key words: antimicrobials, polyhexamethylene guanidine hydrochloride, thermal condensation, synthesis
