采用水溶液聚合的方法合成了二元共聚物——梳形聚合物,并通过正交试验确定了合成特性粘数较高的梳形聚合物最优试验条件:单体总浓度为20%,单体B含量为20%,引发剂浓度为0.2%,反应温度为50℃,pH值等于9。在最优条件下合成的梳形聚合物再进行了水解,并确定了最佳水解条件:水解剂质量分数为8%的NaOH,水解温度为60℃,水解时间3h。最优试验条件下合成的梳形聚合物在最佳条件下进行水解,进而获得梳形聚合物comb-1。
The binary copolymer - comb polymer was synthesized by aqueous solution polymerization. The optimum experimental conditions for the synthesis of comb polymer with higher intrinsic viscosities were determined by orthogonal test: the total monomer concentration was 20% The B content is 20%, the initiator concentration is 0.2%, the reaction temperature is 50 ° C and the pH is equal to 9. Under optimum conditions, the comb polymer was further hydrolyzed, and the optimal hydrolysis conditions were determined: NaOH with 8% hydrolyzate, hydrolysis temperature 60 ℃ and hydrolysis time 3 h. Under optimum conditions, the comb polymer synthesized under optimal conditions was hydrolyzed to obtain comb polymer comb-1.
