| Abstract: | Polycaprolactam(PA6) was synthesized with caprolactam by vacuum polymerization using concentrated phosphoric acid as the catalyst,water as initiator and nitrogen as protective gas at established condition.The influences of various conditions such as the reaction temperature,the reaction time and amounts of concentrated phosphoric acid on the translational ratio of caprolactam were investigated in detail.Results indicated that when the mass ratio of caprolactam and concentrated phosphoric acid is 100:2 and t... |
