摘要

合成了聚丙烯酸（PAA）和丙烯酸-马来酸共聚物（P(AA-co-MA)），研究了自由基聚合的缓蚀效果。用滴定法测定了碳酸钙沉积物的缓蚀效果。丙烯酸均聚物的效率最好。研究了一定分子量PAA的抑菌能力。碳酸钙沉积物对PAA的缓蚀效果在2000 Mw左右。并确定了链式生长调节剂的链接性质对PAA抑制能力的影响。聚合物链中亚硫酸盐官能团的存在有助于提高其抑制能力。

Polyacrylic Acid as an Effective Inhibitor of the Calcium Carbonate Deposits

Polyacrylic acid (PAA) and copolymer of acrylic and maleic acid (P(AA-co-MA)) are synthesized to study the inhibition efficiency by radical polymerization. The inhibition efficiency of calcium carbonate deposits is determined by titrimetric method. Homopolymer of acrylic acid shows the best efficiency. The inhibitory ability of PAA of certain molecular weight (MW) is studied. The highest inhibition efficiency of calcium carbonate deposits is observed for PAA with M_w around 2000. The influence of the nature of links of the chain growth regulator on the inhibitory ability of PAA is also established. It is noted the presence of sulfite functional group in the polymer chain contributes to better inhibitory ability.
