摘要：苯硼酸共聚物可以与存在于黄原胶糖环单元结构中的伯、仲醇羟基通过硼酸酯键形成动态共价微交联结
构的性质对黄原胶进行改性。以偶氮二异丁基脒二盐酸盐为引发剂，通过水相自由基聚合，制备了一系列的丙
烯酰胺（AM）、N-(3-二甲氨基丙基)丙烯酰胺（DMAPAM）和 3-丙烯酰胺基苯硼酸（AMBB）的三元共聚物
1
P(AM-co-DMAPAM-co-AMBB)。通过 HNMR、FTIR、元素分析和光散射对共聚物结构及重均相对分子质量进
行了表征，并对其与黄原胶复配体系的增黏性、流变性、抗老化性及抗干扰性进行了评价。结果表明，P(AM-co-
DMAPAM-co-AMBB)对黄原胶溶液具有明显的增黏性，其中苯硼酸单体的摩尔分数为 1.0%的样品（P-1.0%）表
现出最好的增黏效果，在质量浓度为 600 mg/L 时，其对质量浓度为 2.0 g/L 黄原胶溶液的增黏幅度达 43.7%，对
8073 mg/L 的矿化水中相同质量浓度黄原胶溶液的增黏幅度高达 56.4%，且复配体系具有良好的抗老化降解性，
对乙二醇和 1,3-丙二醇具有较强的抗干扰性。

Abstract: Benzeneboronic acid polymer can form micro-crosslink net with xanthan gum through dynamic
borate ester bond between benzeneboronic acid and diol of xanthan gum, which can be applied in the
chemical modification of xanthan gum. A series of ternary copolymers P(AM-co-DMAPAM-co-AMBB) were
synthesized via aqueous free radical polymerization of acrylamide (AM), N-(3-dimethylaminopropyl)acrylamide
(DMAPAM) and 3-acrylamide benzene boric acid (AMBB) using 2,2′-azobis(2-methylpropionamidine)
dihydrochloride as initiator. The structure and weight-average relative molecular mass of ternary
1
copolymers were characterized by HNMR, FTIR, elemental analysis and light scattering technique. The
thickening, rheology, aging resistanc and anti-interference properties of composite systems of ternary
copolymers and xanthan gum were evaluated. The results showed that P(AM-co-DMAPAM-co-AMBB)
samples exhibited good tackify performance for xanthan gum solution. Among them, P-1.0% sample
prepared from 1.0% mole fraction of benzene boric acid showed the best effect. The P-1.0% sample (600
mg/L) made the viscosity of xanthan gum pure aqueous solution (2.0 g/L) increased by 43.7%, and that of
the same mass concentration of xanthan gum in mineralized water (8073 mg/L) increased by 56.4%.
Besides, the composite system exhibited good aging resistance and obvious anti-interference to glycol and
1,3-propanediol.
