摘要: Butyl acrylate-acrylic acid copolymer and poly (butyl acrylate) were synthesized via suspension polymerization by using butyl acrylate as the main monomer acrylic a secondary monomer. Then these polymers swollen in ethanol hydrolyzed an aqueous solution of sodium hydroxide. Finally, water-soluble polyacrylates obtained washing drying resultant. The influence mass fraction feed ratio, swelling time, hydrolysis time on hydrophilicity, solubility, absolute viscosity prepared was researched. In addition, Ubbelohde viscometer used to determine intrinsic solutions polyacrylates. Mark–Houwink equation applied calculate their average molecular weight. chemical structures heat resistance properties analyzed nuclear magnetic resonance spectroscopy thermogravimetric analy...
