| 摘要 |
The invention relates to the preparation of hydrophobic modified diquaternary cationic monomers and their copolymer as well as the use such monomers and copolymers as thickening agents/rheology modifiers for acidic compositions. The hydrophobic modified diquaternary cationic monomer having the general formula (I): wherein X is selected from O, NH , or NR; Y is any alkyl, alkylene with or without heteroatoms, and R<0>, R<1>, R<2> R<3>, R<4>, which are identical or different, are selected from C1-C4 alkyl groups, R is selected from any alkyl group with or without heteroatoms, and R<5> is a hydrphobe having an alkyl chain of more than 4 atoms. |
