摘　　要：以聚乙二醇-200(PEG-200)和马来酸酐(MA)为原料,合成多官能度烯类支化单体(PM),与丙烯酸(AA)单体通过自由基共聚法制备系列水溶性非线型共聚物PMAAs。通过FTIR、1HNMR和13CNMR对支化单体和聚合物的结构进行了表征。制备的系列非线型共聚物PMAAs作为高吸收铬鞣助剂进行应用实验,结果表明,该高吸收铬鞣助剂在浸酸工序加入时效果最佳,当质量分数为1.5%时,铬吸收率最高可达96.57%,且皮革粒面细致,鞣后皮革的Ts和物理力学性能明显提高。Polyether maleic acid monoester（PM） was prepared by the esterification of polyethylene glycol（PEG-200） and maleic anhydride（MA）.PM was used as an allyl branching monomer to copolymerize with acrylic acid（AA） and the initiator ammonium persulfate to prepare the non-linear copolymer（PMAA） by free radical water-solution polymerization.The structure of PM and PMAA was characterized by means of FTIR,1HNMR and 13CNMR.The prepared non-linear copolymers（PMAA） additives as high exhaustion chrome-tanning auxiliary were applied in the chrome-tanning process.The results indicate that the high exhaustion chrome-tanning auxiliary had the best tanning effect when applied in pickling and when its mass fraction was 1.5%,with the absorptivity of chrome being 96.57%,bring about fine leather surface and significantly increasing the Ts and physical mechanical performance of the leather.
