中文摘要:
      以丙烯酰胺(AM)、丙烯酸(AA)、环糊精改性超支化功能单体(MAH-β-CD-HPEA)、甜菜碱(DEPS)为原料合成了四元共聚物PADAH。考察了引发剂质量分数、AM与AA质量比、DEPS与MAH-β-CD-HPEA质量比对聚合物溶液黏度的影响。最佳合成条件为:AM与AA的质量比为2:1(共占单体总质量的85%),DEPS与MAH-β-CD-HPEA的质量比为14.5:0.5(共占单体总质量的15%),引发剂质量分数为0.3%。性能研究表明,该共聚物的质量浓度为2000 mg/L时,溶液黏度可达647 mPa?s,3500 r/min 剪切20s后黏度保留率高于80%;90℃时,PADAH的黏度为237 mPa?s,黏度保留率为37.5%,均优于PADA(无超支化单体)和普通部分水解聚丙烯酰胺(HPAM)。
英文摘要:
      A hyperbranched polymer PADAH was synthesized by acrylamide(AM), acrylic acid(AA), cyclodextrin-modified hyperbranched functional monomer (MAH-β-CD-HPEA) and betaine (DEPS). The effects of initiator dosage, mass ratio of AM and AA, mass ratio of DEPS and MAH-β-CD-HPEA on the polymer solution viscosity were investigated. The results indicated that the optimum polymerization conditions were obtained as follows: initiator dosage of 0.3%, m(AM):m(AA)=2:1(85% of the total mass of the monomer),m(DEPS):m( MAH-β-CD-HPEA)=14.5:0.5(15% of the total mass of the monomer). The solutions properties of PADAH were evaluated. The results showed that the viscosity of 2000 mg/L polymer solution could reach 647 mPa?s, and the viscosity retention rate after shearing for 20 s was more than 80%, at 90°C, the viscosity of PADAH was 237 mPa?s and the viscosity retention rate was 37.5%, Compared with PADA(no hyperbranched functional monomer) and the partially hydrolyzed polyacrylamide (HPAM), PADAH has better solution properties.
