摘　　要：考察了一种丙烯酸-聚醚改性丙烯酸酯共聚物HS-C的结构特征、聚合物性能(螯合性、抗沉积性)以及表面活性(表面张力、临界胶束浓度、润湿性、乳化性、起泡性和去污力)。并分别对比了HS-C与常用螯合剂、抗再沉积剂以及表面活性剂在不同方面的性能。结果表明,HS-C的螯合值为554.70 mg/g,其螯合性能优于EDTA·4Na及GLDA·4Na,但略低于未改性的丙烯酸盐聚合物PM;其抗炭黑沉积性能与市售抗再沉积剂SRP接近,而PM无抗炭黑沉积作用。在表面活性方面,HS-C的临界胶束浓度和平衡表面张力分别为0.005%和41.85 mN/m;其润湿性能和泡沫性能比LAS、AEO-9、AES相对差,但乳化能力比低分子表面活性剂更好;HS-C具有比LAS更加优越的去污性能,与LAS、AEO-9、AES复配时存在协同增效去污的作用。An acrylic copolymer modified with surface active groups(HS-C)was studied.Its structural characteristics,polymer properties(chelation and antideposition)and surface activity(surface tension,critical micelle concentration,wettability,emulsification,foaming and detergency)were investigated.The performance of HS-C was compared with that of commonly used chelating agents,anti-redeposition agents and surfactants,respectively.The results of FT-IR showed that the main structure of HS-C was similar to that of unmodified sodium polyacrylate(PM),but with more unsaturated bonds and alcohol and/or ether groups.The experimental results showed that the chelation value of HS-C was 554.70 mg/g,which was higher than that of EDTA·4Na and GLDA·4Na but slightly lower than that of PM.Its anti-deposition performance to carbon black was close to that of commercially available anti-redeposition agent SRP,whereas PM had no anti-deposition effect to carbon black.The critical micelle concentration and equilibrium surface tension of HS-C were 0.005%and 41.85 mN/m,respectively.Its wetting and foaming properties were relatively poorer than those of LAS,AEO-9 and AES,but its emulsifying ability was better than that of low-molecular-weight surfactants.HS-C had detergency superior to LAS,and there was synergistic effect when combined with LAS,AEO-9 and AES.
