摘要:
A detergent composition having at least two components. The first component is from 14 to 50 wt % surfactants. The second component is from 0.05 to 4 wt % of a polymer which has polymerized residues of 40 to 65 wt % C1-C18 alkyl (meth)acrylates and 25 to 55 wt % C3-C6 carboxylic acid monomers.
摘要:
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.
