SIMULATION OF HYDROLYTIC POLYMERIZATION OF CAPROLACTAM——EFFECT OF BIFUNCTIONAL REGULATOR ON DISTRIBUTION OF POLYMER COMPOSITIONS

A simulation model dealing with the kinetic behavior of the hydrolytic polymerization of caprolactam with bifunctional regulator is proposed to analyze such characteristic data of the polymerization as the concentrations of caprolactam,cyclic dimer,as well as conversion, number average and weight average polymerization degrees ,and polydispersity indexs The calculated values based on the model agree well with the experimental data The results show that the number average polymerization degree (NAPD) decreases with increasing concentrations of water,aminocaproic acid and relative molecular mass regulator(RMMR) and that the effect of the concentration of water is more obvious, while NAPD does not basically change when the concentration of RMMR is smaller than 0 0068 mol·kg -1 and NAPD decreases when it is greater than 0 068 mol·kg -1 . NAPD also decreases with the increase of concentration of water when the concentrations of aminocaproic acid and RMMR are equal to zero
