Freeze-thaw stability emulsion polymer and novel reactive surfactant for its coating

摘要

The invention provides aqueous coating composition having freeze thaw stability, comprising: (a) at least one latex polymer derived from at least one monomer and at least one reactive surfactant of the formula R1O(CH2CHR2O)x(CH2CH2O)y(CH2CHR3O)zR4 where R1 is either alkyl, aryl, alkylaryl, or aralkylaryl of 8-30 carbon atoms, R2 is CH2OCH2CHCH2 (AGE); R3 is either H, CH3, or CH2CH3; R4 is H or SO3M or PO3M where M is H or K, Na, NH4, NR4, alkanolamine, or other cationic species and x=2-100; y=4-200 and z=0-50.
