| 摘 要： | 采用顺丁烯二酸酐对超支化聚酯(HBPE)末端基的改性得到新的端丙烯酸基超支化聚合物(AHBP),用Na0H中和可得水溶性端内烯酸基超支化聚酯(AHBP-Na).利用AHBP-Na作为水溶性共聚单体,研究其对丙烯酸酯乳液的改性影响.研究表HfJAHBP-Na可以用于乳液聚合,且用量以占单体总量的1%～3%较为合适.所得乳胶粒粒径为106～116 nm,粒径多分散系数PDI为0.058～0.067,乳液黏度下降33%～43%,且能显著提高其耐水性,并可使乳胶膜硬度提高三个等级,从3B升到HB.AHBP-Na的加入还可以提高乳液的稳定性,当加入单体量3%的AHBP-Na时,可使乳液钙离子稳定性提高3倍.

| Abstract: | Hydroxy-terminated hyperbranched polyester(HBPE)was modified by maleic anhydride to get acrylateterminated hyperbranched polyester(AHBP)which could be counteracted with NaOH to obtain water-soluble acrylateterminated hyperbranched polyester.Effects of water-soluble acrylate-terminated hyperbranched polyester used as copolymerization monomer on modification of acrylate emulsion were studied.Testing results showed that watersoluble acrylate-terminated hyperbranched polyester could be used for emulsion polymer... |
