摘　　要：采用乳液聚合法制备丙烯酸丁酯-苯乙烯(BMA-St)共聚物浆料,研究BMA-St浆料与醋酸酯淀粉、PVA 0588的浆液和浆膜性能。结果表明,BMA-St共聚物红外光谱中存在酯基(1156cm^(-1))和苯环(763cm^(-1))特征峰;与纯BMA-St浆料相比,BMA-St浆料与醋酸酯淀粉、PVA0588配比为15∶2∶3时,混合浆料所制备浆膜黏附力可达164.08 N,浆膜耐屈曲性提高1.30%;浆纱时黏度稳定性提高2.40%,浆纱增强率提高6.00%,毛羽损失率降低10.85%,合成浆料更适用于涤纶纱上浆。Butyl acrylate styrene copolymer(BMA-St)slurry was prepared by emulsion polymerization.The compatibility of BMA-St slurry with acetate starch and PVA 0588 was studied.The results showed that the characteristic peak of ester groups(1156 cm^(-1))and the benzene ring(763 cm^(-1))were existed in FTIR of BMA-St copolymer.When the ratio of abovementioned sizing agent was controlled as 15:2:3,compared with BMA-St slurry,the adhesive force of the mixed slurry film was up to 164.08 N,and the buckling resistance was increased by 1.30%.The viscosity stability and sizing reinforcement ratio were increased by 2.40%and 6.00%respectively.The hairiness loss rate was decreased by 10.85%,which demonstrated that the synthetie size was more suitable for sizing polyester roving.
