In this paper, a kind of environmental resin which has the advantage of acrylic acid resin and polyester resin was prepared by modification to polyester resin with acrylic acid pre-poly, Lots of conditions that affect the preparation of acrylate prepolymer and the process of esterification and condensation polymerization were also discussed in this paper. By using amino resin as curing agent, the properties of filming of water soluble acrylic acid modified ployester was studied, which has solved the compatibility issue between polyester resin and amino resin.%采用丙烯酸酯预聚物对聚酯树脂进行改性的方法,制备出兼具丙烯酸树脂和聚酯树脂优点的环保型树脂,探讨了影响丙烯酸酯预聚体制备及酯化缩聚反应工艺过程的各种影响因素,并以氨基树脂为固化剂,考察了水溶性丙烯酸树脂改性聚酯树脂成膜的性能,解决了聚酯树脂与氨基树脂的相容性问题.
