摘要： 兼含离子型取代基(羧烷基钠盐)和非离子型取代基(羟烷基)的羧烷基羟烷基纤维素(CAHAC)复醚,由于其结构特点和性能优点,已愈来愈广泛地为人们所重视[1-3]。有关其有机交联改性或无机交联改性的研究结果表明,在耐热增稠剂、耐盐吸水材料[4]、尤其是在油田开采化学方面,CAHAC都有很大的发展前途。

Abstract: The interaction between carboxymethyl hydroxyethyl cellulose and carboxymethyl hydroxypropyl cellulose and organie zirconium compounds has been investigated. A buffer system was developed to control the formation of gel. Experimental results show that both zirconium acetyl acetonate and zirconium lactatecan crosslink carboxyalkyl hydroxyalkyl cellulose successfully. The crosslinked product exhibits better heat-resistant stability.

Key words: organic zirconium, carboxyalkyl hydroxyalkyl cellulose, crosslinking, thermal stability
