Claims13
A copolymer obtained from a free-radical copolymerization of polymerizable monomers consisting of
- a) 25.0 to 80.0 mol % of at least one cationic monomer is diallyldimethylammonium chloride, and
- b) 1.0 to 4.4 mol % of at least one polyethylene glycol macromonomer,
- c) 15.6 to 74.0 mol % of at least one uncharged acrylamide monomer, and
- d) optionally, up to 30.0 mol % of at least one monomer other than monomers of components a), b) and c),
- wherein each of the at least one polyethylene glycol macromonomer of component b) is a monomer of the formula:
- H2C═CRx—O(CH2)4—O—(CH3H6O)l—(CH2CH2O)p—H
- in which
- RX is H or methyl,
- on molar average is a number from 0 to 7, and
- p on molar average is a number from 2 to 150.
A method for achieving one or more effects selected from producing a shine, hydrophilization, and achieving a repair effect on a hard surface, the method comprising a step of contacting the hard surface with at least one composition comprising at least one copolymer obtained from a free-radical copolymerization of at least components a), b) and c)
- a) 25.0 to 80.0 mol % of at least one cationic monomer selected from the group consisting of cationic (meth)acrylamide monomers and diallyldimethylammonium chloride, and
- b) 1.0 to 50.0 mol % of at least one polyethylene glycol macromonomer, and
- c) 15.0 to 74.0 mol % of at least one uncharged acrylamide monomer, wherein each of the at least one polyethylene glycol macromonomer of component
- b) is a monomer of the formula:
- H2C═CRx—O(CH2)4—O—(CH3H6O)l—(CH2CH2O)p—H
- in which
- RX is H or methyl,
- l on molar average is a number from 0 to 7, and
- p on molar average is a number from 2 to 150.
