A method for preparing hydrophobically modified rheology modifiers; said method comprising polymerizing a monomer mixture having two or more components. The first component is H2C=C(R)C(O)X(CH2CH2O)n(CH(R')CH2O)mR" or H2C=C(R)C6H4C(CH3)2NHCO2(CH2CH2O)n(CH(R')CH2O)mR", wherein X is O or NH, R is H or CH3, R' is C1-C2 alkyl, R" is C8-C22 alkyl or C8-C16 alkylphenyl, n is an average number from 6-100 and m is an average number from 0-50, provided that n≥m and m+n is 6-100. The second component is a C3-C6 carboxylic acid monomer; wherein polymerization occurs in the presence of an oxidant, a reductant and a metal catalyst, and substantially in the absence of a peroxide, hydroperoxide or perester containing an alkyl group having at least five carbon atoms.
一种制备疏水性改性流变修饰剂的方法;所述方法包括聚合具有两种或两种以上组分的单体混合物。第一种组分是 H2C=C(R)C(O)X(CH2CH2O)n(CH(R')CH2O)mR" 或 H2C=C(R)C6H4C(CH3)2NHCO2(CH2CH2O)n(CH(R')CH2O)mR" 其中 X 是 O 或 NH,R 是 H 或 CH3、R'为 C1-C2 烷基,R "为 C8-C22 烷基或 C8-C16 烷基苯基,n 为 6-100 之间的平均数,m 为 0-50 之间的平均数,条件是 n≥m 且 m+n 为 6-100。第二组份为 C3-C6 羧酸单体;其中聚合是在氧化剂、还原剂和金属催化剂存在下,且基本上不存在过氧化物、过氧化氢或含有至少五个碳原子的烷基的过氧化物的情况下进行的。
