硼酸酯共聚物P(DB/BS14-AM-AMPS)的合成及性能的初步研究

Preliminary Study on Synthesis and Performance of Boric Acid Ester Copolymer P(DB/BS14-AM-AMPS)

利用可聚合硼酸酯DB/BS14与丙烯酰胺(简写为AM)、2-丙烯酰胺基-2-甲基丙磺酸(简写为AMPS)合成三元共聚合产物P(DB/BS14-AM-AMPS),对其进行红外表征以及耐温、抗盐的测定。实验结果表明,三元共聚物P(DB/BS14-AM-AMPS)具有一定的耐温和抗盐性能。在一定的水解度范围内,单体水解度的改变没有明显改变共聚物P(DB/BS14-AM-AMPS)溶液的耐温性能,但是共聚物溶液的抗盐性能却发生显著变化。

The terpolymer P（ DB/BS14- AM- AMPS） was synthesized by boric acid ester DB/BS14 containing aggregated double bonds,acrylamide（ AM）,2- acrylamide- 2- methyl propane sulfonic acid（ AMPS）. The infrared characterization,temperature tolerance and salt-resisting properties were studied on terpolymer P（ DB/BS14-AM-AMPS）. It can be concluded that P（ DB/BS14-AM-AMPS） had certain temperature tolerance and salt-resisting properties. Within a certain degree of hydrolysis,when the degree of hydrolysis of monomer was changed,there was no obvious change of the heat resistance performance of copolymer P（ DB/BS14- AM-AMPS） solution,but the salt resistance performance of the copolymer solution had a change significantly.
