| 摘 要： | INTRODUCTIONS:Alkyl Ketene Dimer (AKD) has been used as a sizing agent for more than 50 years in papermaking process. Sauer [1] synthesised the first AKD in 1947 before Downey [2] developed and patented it in 1953. Since then, many modifications have been made to the AKD emulsion with introduction of starches and polymers to optimise the sizing efficiency, stability of the emulsion and also to reduce the AKD hydrolysis rate [3, 4]. Cationic starches were developed in the 1960s to ov…
