Properties of aqueous solution of comb - like amphiphilic polymers
摘要
Abstract
The aggregation behaviors, rheological properties and dispersing performance with respect to carbon black of three comb - like amphiphilic polymers, poly ( styrene -co - maleic anhydride ) - g - (poly ethylene glycol monomethyl ether) ( A) , poly ( styrene -co - maleic anhydride) - g - C12 H25 OH ( B ) and poly ( styrene - co - maleic anhydride) -g- (poly ethylene glycol monomethyl ether + C12H25 OH) (C) were investigated. Results showed that various dispersing spherical aggregates with particle size from tens to hundreds nanometer can be formed in aqueous solution of the aforesaid comb - like amphiphilic polymers, and the size distribution is quite wide. At 25 ℃ , results from study of rheological properties of the aqueous solution of A, B and C with various mass concentration showed that, at same mass concentration, samples with higher hydrophobic performance will cause stronger shear thinning behavior of aqueous solution of the samples. Under same conditions, sequence of dispersing performance of three samples with respect to carbon black are B > C > A, and the dispersing performance will increase with increase of hydrophobicity as well as mass concentration of the samples in aqueous solution.关键词
