Lard oil carrying on ester exchange and was esterified with maleic anhydride to produce lard oil-maleic acid monoester, then amphiphilic muti-function fatliquors was obtained by copolymerizing with lard oil maleic acid monoester and acrylic acid monomer. The optimum conditions of synthesis were obtained by studying the effects of the factors in reaction. The optimum conditions of the ester exchange reaction were temperature 60℃, the amount of sodium methoxide 0.2%(based on lard oil) and time 35 min .The ester reaction was carried out under the condition of 130℃for 3 h, and the conditions of copolymerizing were as follows: the mass fraction of modified lard oil and initiator were 40% and 0.7% (based on total monomer), the mass concentration of monomer was 30%, the temperature of reaction was 80℃.
