摘要： 研究了在超声波作用下羧甲基纤维素(CMC)的降解反应及CMC与具有不同亲水亲油比值的活性大单体[烷基醇(酚)聚氧乙烯醚丙烯酸酯及第三单体(苯乙烯)]的超声共聚反应.经萃取提纯的共聚产物用IR、13CNMR和UV等方法进行表征,证实通过超声反应制得了二元和三元共聚物.超声反应时间及单体投料量对共聚物组成影响较大,共聚物具有较好的增粘能力和较高的表面活性.

Abstract: The copolymerization by ultrasonic irradiation of carboxy methyl cellulose(CMC)with macromonomer (alkyl poly (etheroxy) acrylate) and comono-mer(styrene) was studied.The purified products were characterized by IR, 13C NMRand UVspectra, the results show that the copolymer prepared is mainly a block one. Ultrasonic irradiation time and monomer weight fraction in the feed have great influence on structure and properties of copolymers.Copolymers prepared by ultrasonic irradiation have a high viscosity and a good surface activi-ty.
