| 摘 要： | 采用胶体滴定法研究了碱的质量分数对N-乙烯基甲酰胺-二甲基二烯丙基氯化铵共聚物(PNVF-DA)水解反应的影响,采用激光光散射仪测定了PNVF-DA水解产物(CPND)的重均分子量(MW)。结果表明:随着碱的质量分数的增加,CPND的胺化度也相应增大;当PNVF-DA中酰胺基与NaOH的摩尔比为1:4,在75℃下反应7h,其胺化度接近100%;胺化度为10%和20%的水解产物CPND-10和CPND-20的MW比未水解的PNVF-DA大,胺化度大于30%的CPND的MW递减。

| Abstract: | The effects of the mass fraction of NaOH on the hydrolysis reaction of N-vinylformamide-diallyldimethylammonium chloride copolymer(PNVF-DA) were investigated using colloidal titration.The molecular weight(Mw) of hydrolysates(CPND) of PNVF-DA were determined using multi-angle laser light scattering instrument in pH=4.6 NaAc-HAc buffer solution.The results indicated that the amination degree of CPND increased with the increase in the mass fraction of NaOH.The amination degree of CPND was near to 100% under the conditions of the mole ratio(1:4) of the amide groups in the copolymer and NaOH at 75℃ for 7h.The Mw of CPND-10 and CPND-20 with amination degrees of 10% and 20% were larger than PNVF-DA.The Mw of CPND with amination degree of more than 30% decrease gradually. |
